BASIC STUDY ON MECHANICAL CHARACTERISTIC OF FRICTION SURFACE BETWEEN ALUMINUM-SPRAYED STEEL PLATE AND BLASTED STEEL PLATE

Abstract

For developing high-strength bolted friction joints with much higher friction coefficients than conventional ones, basic slip tests are conducted by changing the values of contact pressure for friction joints with aluminum-sprayed splice plates. The results show that friction coefficients of aluminum-sprayed friction surface in the area of higher contact pressure are lower rather than conventional friction coefficients. These results are in accordance with a previously-proposed friction theory.
