Study of frictional wear properties of materials for mechanical seals

Abstract Wear of seal materials is a widespread problem in the aerospace, petrochemical, and electric power fields, leading not only to low efficiency mechanical equipment, but also increased energy consumption reduced safety performance. Therefore, this paper establishes SCA-wear model based on tensile constraint algorithm calculate analyze friction wear performance materials. The coefficients different loads at 200°C 10 min after test time stabilize, fluctuate range 0.35 30N, 0.26 70N, 0.48 90N. frictional C/C composite material least 15.6%. reason that it composed entirely carbon. It has many advantages carbon graphite low.
