Q3) How Corrosion Impacts Fastener Performance and Longevity
Ans) Corrosion significantly impacts fastener performance and longevity,
especially in environments where moisture, humidity, and corrosive agents are
present. Corrosion is the chemical reaction between a metal fastener and its
surroundings, leading to the deterioration of the fastener's material over time.
Here are some key ways in which corrosion affects fastener performance and
longevity:
1. Weakening of Fastener Strength: As corrosion progresses, it gradually
weakens the fastener's material. The once strong and reliable material
becomes more susceptible to deformation, fracture, or failure under load,
compromising the overall structural integrity of the assembly.
2. Loosening and Loss of Clamp Load: Corrosion can cause the fastener to lose
its grip on the mating components. The chemical reaction weakens the bond
between the fastener and the material it secures, leading to loosening over
time. This loss of clamp load can lead to component movement, reduced joint
integrity, and eventual failure.
3. Thread Damage and Galling: Corrosion can damage the threads of a
fastener, making it difficult to assemble or disassemble. Galling occurs when
mating threads seize or lock together due to corrosion, leading to thread
damage and potential jamming, making it challenging to remove the fastener
without causing additional damage.
4. Reduced Corrosion Resistance of Coatings: Fasteners with protective
coatings, such as zinc plating or galvanization, are designed to resist corrosion.
However, once the coating is compromised, such as through scratches or chips,
the underlying metal becomes vulnerable to corrosion, accelerating the
degradation process.
