Abstract
Rhenium-Iridium(Re-Ir) thin films were deposited onto the tungsten carbide(WC) molding core by sputtering system. The Re-Ir thin films on tungsten carbide molding core were analyzed by scanning electron microscope(SEM) and surface roughness. The Re-Ir coating technique has been intensive efforts in the field of coating process because the coating technique and process have been their feature, like hardness, high elasticity, adrasion resistance and mechanical stability and also have been applied widely the industrial and biomedical areas. In this report, tungsten carbide(WC) molding core was manufactures using high performance precision machining and the efforts of Re-Ir coating on the surface roughness.
초경합금 성형용 코어를 이용한 고온 압축 성형방식으로 제작되기 때문에 성형용 코어의 초정밀 연산 가공 및 코어면 코팅 기술 개발이 시급한 상황이다. 따라서 본 연구에서는 성형용 초경합금 코어의 연삭가공을 수행하고, 가공 완료된 성형용 코어의 가공면에 Re-Ir 코팅을 수해, 측정을 통하여 코팅면의 마찰 계수 변화에 대한 연구를 수행하였다.
