Preparation of Al-SiCp Composite Coating by Plasma Thermal Spray

플라즈마 용사에 의한 Al-SiCp 복합재료 코팅층의 제조

  • Published : 2003.05.01

Abstract

Al-SiC$_{p}$ composite layer was prepared by plasma thermal spray on aluminum substrate using composite powder prepared by mechanical alloying. Mechanically alloyed powder was achieved after 24 h milling, which was used for thermal spray coating. The correlations between process conditions and thickness/porosity were analyzed, and increase of hardness was confirmed. The presence of Al-Si-C-O compound was detected by TEM analysis.

기계적 합금화법에 의해 준비된 복합분말을 이용하여 용사공정에 의해 알루미늄 모재에 Al-SiC$_{p}$ 복합재료 코팅층을 형성하였다. 24h milling 후 복합화된 분말을 제조할 수 있었으며, 이 분말을 용사하여 복합재료 코팅층을 형성할 수 있었다. 코팅층의 두께 및 기공율과 공정변수와 관계를 분석하였으며, 경도의 증가를 확인하였다. 또한 TEM분석에 의해 Al-Si-C-O 화합물의 존재를 확인하였다.
