航空发动机篦齿类零件封严涂层制备工艺及涂层厚度测量对应关系的建立

为了达到对篦齿类零件封严齿上涂层厚度和涂层质量的控制,采用转换测量对象,建立封严齿与转换对象间涂层厚度及涂层质量特性的对应关系,在零件后续批生产过程中,实现对篦齿类封严件上涂层厚度的控制以及涂层性能的检验,确保零件上涂层厚度及涂层质量特性与其转换测量对象之间具有相应的对应关系。

Aero-engine Seal Applications Thermal Spray Technical Process and Cut-up Thickness VS Coupon Correlation Establishment

For the ease of acquiring optimum thermal spray coating thickness and high quality,typically adopting transfer measure object on coupon to establish correlation of coating thickness and coating quality characteristic to seal teeth and converting objects,using established correlation to monitor thermal spray thickness and voids/porosity for production parts.
