Analysis of Wear Behavior of Friction under Oil Lubrication of Powder Metallurgy Materials
This paper studied the friction and wear properties of powder metallurgy under oil lubrication.The influences of the addition of Mo,P and C on the microstructure,hardness and wear properties was studied.The wear mechanism in this experimental condition was discussed.At the same time,the wear resistance of the powder metallurgy and casting was compared.The results showed that:the addition of Mo,P can increase the hardness of material.Mo can inhibit the generation of pearlite and promote the generation of bainite.The affection of P's addition on the microstructure and properties are complex.The wear resistance Fe-0.9C-1.2Cu iron-based powder metallurgy and casting were similar.The material added Mo,P,increased C had better wear resistance than casting.Under this condition,power metallurgy has abrasive wear morphology,while casting has abrasive wear and fatigue spall morphology.
