Microstructure and Hardness of Al-Cu Alloy Coating on Monel 400 by Hot Dipping
액상 침적에 의한 Monel 400기지상에 형성된 Al-Cu 합금 코팅층의 조직 및 경도
Abstract
The structure of coating layer formed by hot dip Al-Cu alloy coating on Monel 1400 metal was studied. The coating layer consists of alloyed layer adjacent to the Monel 400 substrate and Al-Cu alloy. It was found that the hardness of coating increased with dipping time and heat treatment associated with the diffusion and the formation of intermetallic compound at the interface. However the thickness of coating layer was decreased at high dipping temperature due to tile higher viscosity of liquid coating alloy. Diffusion heat treatment at
