Investigation of composite coated Ti-C-N surfaces with ball-cratering test method

Abstract

We present the performance of dry sliding metal-metal wear performance of AISI SS410 and Ti-C-N coated specimens at room temperature. In this investigation, the ball cratering abrasive wear testing method was used with a various loads of 2N, 3N and 4N, with total sliding distance of 353.43 m and at a constant sliding speed of 0.3927 ms-1. In this testing machine the abrasive ball of high carbon steel with 750 HV at 100 g load is rotated against the Ti-C-N composite coated and uncoated AISI SS410. The worn surfaces were examined with scanning electron microscopy (SEM) (with EDAX attachment). The more grooving region, pits, ploughing ridge were found on the worn surface of the high carbon steel.
