Abstract:

A friction and wear machine was developed to simulate the frictional characteristics of reciprocating weapon components. The machine was used to evaluate the various factors influencing the friction of phosphate coatings. Coefficients of friction for the coatings were determined under static and dynamic conditions. The following factors influencing the coefficient of friction are considered type of coating, lubrication, loading weight, surface roughness, crystalline structure, and velocity. The coefficients of friction for manganese phosphate coatings did not differ to any practical extent from the coefficients for zinc phosphate coatings. Lubrication is a significant factor on the coefficients of friction for phosphate coatings. The coefficient of friction was independent of the applied load. Velocity during dynamic testing, surface finish, and crystalline structure influenced the coefficient to a slight degree. Procedure is given, and results are discussed.
