Analysis of the Effect of Various Factors on Metal Transfer and Wear between Specimen Pairs of Same Metal and Same Shape. I. The Basic Scheme of Formulation of Metal Transfer and Wear

Abstract

The fundamental scheme of formulation of the amount of metal transfer and wear is based upon the theory suggested in the previous paper [J. Appl. Phys. 23, 1011–1019 (1953)]. The basic terms used in formulating metal transfer and wear are (1) the potential amount of metal transfer Mt*; (2) the mechanical factor of the chance of metal transfer φm; (3) the thermal factor of the chance of metal transfer ψθ; and (4) the adhesion factor of the chance of metal transfer Xa. The expression for the amount of metal transfer Mt from one specimen to another is Mt=Mt*φmψθ, when ψθ is bigger than Xa, and is Mt=Mt*φmXa when Xa is bigger than ψθ. The equation for the amount of wear Mw represented by the weight loss of a specimen is Mw=Mt*φm (1-ψθ), when ψθ is bigger than Xa, and is Mw=Mt*φm (1-Xa), when Xa is bigger than ψθ.
