采用等离子喷涂技术在铝合金表面喷涂一层薄的Ni/Al过渡层,再进行搪烧,以提高瓷层与基体的结合强度。实验结果表明,通过等离子喷涂,熔融的Ni/Al粉末被雾化后高速撞击到铝合金表面,与基体牢固结合,涂搪烧结后,瓷层与基体间的结合强度显著提高,瓷层的裂纹和脱瓷现象得到控制。 Plasma spraying technology is used to spray a thin layer of Ni / Al transitional layer on the surface of aluminum alloy and further to reduce the bonding strength between the ceramic layer and the substrate. The experimental results show that the Ni / Al powder melted by plasma spraying is rapidly atomized to the surface of the aluminum alloy by plasma spraying, and firmly bonded with the substrate. After the enamelling sintering, the bonding strength between the ceramic layer and the substrate increases significantly, the crack of the ceramic layer And the phenomenon of porcelain is controlled.
