Titanium occurs naturally combined with other elements and was first discovered in 1791. It has a high strength-to-weight ratio and is resistant to corrosion, making it useful for aerospace and medical applications. Titanium can exist in alpha and beta phases with different crystal structures. Photochemical etching uses light and chemicals to dissolve titanium selectively and create patterns. ACE developed a safer non-HF etching process called TiME and has expanded their business due to its success.

Titanium: A New Generation Material for Architectural ApplicationsIJERA Editor
Advanced Materials are defined as unique combinations of materials, process technologies, that together, help create and capture value by addressing large, global unmet wants and needs of building industry. There is a wide range of innovation enabled by technologies for processing materials and integrating currently available materials for creation of new generation buildings “Titaniun” is one of them. It is an incredibly durable and stunning material known for its wide-range of color, high-tensile strength. Titanium can be processed to achieve a variety of surface textures, from a soft matte to a near gleaming reflectivity suitable for architectural application. Titanium's corrosion immunity, strength and physical properties combine to allow reduced wall thickness, lowering its installed unit cost which is favourable as far as its application in densely populated urban areas is concerned. Many countries like United Sates of America, China, and Spain etc have also stared its use however its use in developing country like India is still limited. The paper attempts to analyze the chemical properties of Titanium as a futuristic building material. It also observes the variant of the material as option to make self-cleaning buildings in the future, reducing the amount of harmful cleansers used currently.
As the titanium has a high melting point, small specific gravity, high strength, good toughness, anti-fatigue, corrosion resistance, low thermal conductivity, high and low temperature tolerance performance, Century fifties began to be recognized, was applied to aviation, aerospace and other high-tech fields. With the continuous promotion of chemical, oil, electricity, desalination, construction, daily necessities and other industries, titanium has been increasingly valued, known as the "modern metal" and "strategic metal" is to improve the level of national defense equipment indispensable Of the important strategic materials.

1. 1
ETCHING OF TITANIUM ALLOYS
Occurrence
Titanium is the 22nd
element in the periodic table and the first element in a group of metals known
as the Transition Metals. It is the 9th
most abundant element in the Earth’s crust and the 4th
most
abundant structural metal after aluminium, iron, and magnesium.
Like most metals, titanium does not occur in nature as a pure metal. Instead, it is found combined
with other elements in the form of minerals. The main titanium minerals are ilmenite (iron and
titanium oxide, FeTiO3) and rutile (titanium dioxide, TiO2).
History
Titanium was first discovered in 1791 in Cornwall by the Reverend William Gregor. The new element
was named Titanium (derived from the Titans, the sons of the Earth goddess of Greek mythology) by
the German scientist Martin Heinrich Klaproth. Titanium was discovered in its natural form as
titanium oxide, and it was not until 1910 that pure titanium metal was produced, albeit on a small
scale, by the American metallurgist Matthew Arnold Hunter at Rensselaer Polytechnic Institute in
cooperation with the General Electric Company in the USA. Hunter obtained titanium by reducing
titanium tetrachloride (TiCl4) using sodium in an evacuated steel bomb.
Properties and applications
The application of titanium and its alloys has seen a rapid growth over the last few decades, mainly
as a result of an attractive combination of high strength and low density. The density of titanium (4.5
g/cm3
) is almost half that of copper and less than 60% the density of stainless steel. The tensile and
yield strengths of titanium are comparable to those of most stainless steels. The resulting high
strength-to-weight ratio accounts for the widespread use of titanium, most notably in the aerospace
industry.
Titanium alloys are also known to possess excellent corrosion resistance. While titanium itself is a
very reactive metal, it exhibits excellent corrosion resistance in practice thanks to its ability to form
an insulating or protective oxide layer upon exposure to oxygen.
Nearly 80% of titanium is used in the aerospace industry. Titanium and titanium-rich alloys have also
found widespread use in medical applications, such as in medical implants, due to their
biocompatibility, corrosion resistance and mechanical strength. Chemical processing is another area
where titanium is used due to its outstanding resistance to aggressive chemical environments.
Alpha and beta titanium
Titanium can exist in two different phases based on the structure of its crystals: the alpha phase and
the beta phase. The alpha phase is a hexagonal close packed structure, while the beta phase is a
body-centred cubic structure. Commercially pure titanium is alpha in structure. Certain alloying
2. 2
elements such as aluminium and tin tend to stabilise the alpha phase, whereas transition metals,
such as vanadium, often stabilise the beta phase. Titanium alloys that support both phases show
improved physical properties compared to alloys in which only one phase is stabilised. In fact, one of
the most widely used titanium alloys contains 6% aluminium and 4% vanadium, hence the name Ti-
6Al-4V (also known as Grade 5 titanium).
Photochemical etching of titanium
While the native oxide film on titanium is very thin (no more than a few nanometres in thickness), it
provides the metal with outstanding corrosion resistance properties. This oxide film is consistent,
continuous, and highly stable, thus insulating the base metal from the surrounding environment. As
a result, titanium alloys are resistant to most oxidising reagents.
Photochemical etching is used to produce patterns and features on metal sheets by selectively
dissolving the metal using an oxidising reagent. Wet photochemical etching of titanium has
conventionally been carried out using hydrofluoric acid (HF) or a mixture of hydrofluoric and nitric
acids. The effective etching reagent is hydrofluoric acid while the optional nitric acid is used mainly
to reduce hydrogen absorption and therefore hydrogen embrittlement. However, there are two
major issues associated with the use of etching solutions containing HF and nitric acid. HF is a major
health and safety hazard. The fluoride ion (generated by the dissociation of HF in water) readily
penetrates the skin, damaging deep tissue layers and bone. Moreover, both HF and nitric acid tend
to attack the photoresist used in the etching process, ultimately causing detachment of the
photoresist.
Recognising the potential of photochemical etching in the manufacture of titanium parts, ACE has
invested in an intensive R&D programme to develop a non-HF process for the etching of titanium
alloys. These R&D efforts have culminated in the development of the TiME process for etching
titanium (both alpha and beta) and nickel-titanium alloys. The new process uses a unique chemistry
that is safer than conventional HF-based solutions. The process also includes a pre-treatment step to
improve photoresist adhesion to the metal, as well as a post-etch treatment process to achieve the
required surface finish (Figure 1).
The recent expansion of the company to double its previous size has been driven in part by the
success of the new TiME process. ACE has invested in a new etching department, including new staff
and state-of-the-art etching, cleaning, measuring and inspection equipment.
Etching can produce complex features and geometries in titanium sheets (Figure 2). Thicknesses
ranging from 25 µm to 1.0 mm can be processed using the TiME process. Moreover, the process
does not affect the chemical and mechanical properties of the metal.
ACE believes in the value of scientific knowledge and research in advancing the state of the
photochemical etching industry. Innovations in this industry can have a huge impact on other
industries which use photo-etched components in the manufacture of their products, such as the
medical, electronic, automotive and aerospace industries.
