Abstract

When a machine is previous terminnext term operation, two moving surfaces interact to generate a large amount of previous termwearnext term particles. The previous termwearnext term debris generated inside the machine or contaminants from outside plays important roles previous terminnext term both two-body and three-body previous termwear.next term For all mining and port machinery, their lubricants are very likely to be polluted by contaminants such as previous termsilicanext term and other metallic debris such as previous termironnext term and nickel. previous termInnext term order to seek a deeper understanding of the effects of different contaminants on previous termwear process,next term this project investigated previous termsliding wear processes when silica powder and iron powdernext term exist previous terminnext term lubricants.

Four previous termsliding wearnext term tests were conducted on a pin-on-disc tester with and without the contaminants. Visual inspection, ferrography analysis, particle quantity analysis using a particle analyzer, and numerical surface analysis using confocal laser scanning microscopy (CLSM) were conducted to study the previous termwearnext term particles and previous termwearnext term surfaces. Supported by the data generated from the comprehensive analyses on the previous termwearnext term particles and previous termwearnext term surfaces, the investigation of the effects of the added contaminants to the previous termwear processes and wearnext term mechanisms have been carried out and presented previous terminnext term this paper.
