1. What material is most susceptible to hydrogen embrittlement?
2. What processes often generate hydrogen?
3. What are three ways to prevent or mitigate hydrogen embrittlement?
4. What is adhesive wear? What are two other terms for adhesive wear?
5. What type of wear is likely to occur in bearings?
1.Hydrogen embrittlement does not affect all metallic materials equally.the most vulnerable are high strength steels,titaniumalloys,and aluminium alloys.
2. Hydrogen production is the family of industrial method for generating hydrogen.
ELECTROLYSIS AND THERMOLYSIS ARE THE TWO PROCESS.
From water electrolysis.chemically assisted electrolysis.radiolysis
photo biologicalwater splitting.photocatalytical water splitting
3.Three ways ;Using proper plating procedures and bake fasteners correctly.
use fastener coatings that do not involve electro plating
use a softer bolt material.
4.it is a phenomenon which occurs when two metals rub to gether with sufficient force to cause the removal of material from the less wear resistant surface.
two terms
sliding wea(or)scuffing wear
5. A cavitation wear and erosion wear is used in bearings.
factors influencing the erosion wear
Particle size.
shape
hardness
velocity
temperature
