Incorporation of solid lubricants into surface of friction parts engineered for high-temperature applications

2. Project Technical Overview
HIGRAPH
„Incorporation of solid lubricants into surface of
friction parts engineered for high-temperature
application“
EU FP7 - Grant agreement no: 606009

3. Industrial Problem and the Project Goal
Since traditional lubricants fail when friction is combined with high
temperature, it is either impossible or impractical to use these materials in
many industrial applications.
The goal of the HIGRAPH project is to provide participating SMEs and the
machinery industry with a novel technology for manufacturing sliding and
other components that enhances dry-friction performance under high
temperatures, increases durability, and extends the lifetime of the parts.
It will be reached by encapsulation of High Temperature Solid-lubricant
(HTSL) particles (WS2, WSe2, h-B) into a micro-sized reservoirs in surface
layers of thermal spray coatings and P/M parts.

4. Technical objectives
o Detailed study of High temperature powder systems
oSimulation of mixed and quasi-hydrodynamic lubrication by HTSL
oTribological testing in wide temperature range of 100°C-700°C
o Production of sliding and other components with composite surface layers
containing HTSL particles encapsulated in residual pores or micro-reservoirs
o Wide range of industrial trials of high temperature self-lubricated frictions
parts and demonstrate increase of their lifetime

5. The main exploitable project results
o Database on end-users high temperature: friction parts, thermal
spray coatings and solid lubricant materials
o P/M technology for production of self-lubricating sliding and other
components intended for application under high temperatures
o Technology for modification of surface of thermal spray coatings
with high temperature solid lubricants.
o On-line process control system for coating deposition technologies

6. Project impact
o Industrial implementation of self- lubricating materials with improved
tribological properties
oDecrease waste generated in industry due to increase of parts lifetime
o Longer lifetime, which will result in lower amortization costs industry-
wide
oLess production outages due to failure of machine parts
oImprove competitiveness of coating and surface treatment SME
oAvailability of a critical technology on European market
