Abstract

When applying a vacuum-arc discharge plasma coating to profilecomposite items, such as twin turbine blades, unicycle blades, etc., a problem might occur with ensuring the tolerance on the coating thickness. This article presents the obtained dependence of the nonuniformity of the coating thickness on the geometric parameters of the inter-blade channel—its length and width. We develop a simulation model for calculating the distribution of the thickness of the vacuum-arc discharge plasma coating for the profilecomposite parts having shadow zones.

真空电弧放电等离子涂层厚度不均匀性对刀间通道几何参数的依赖性

摘要

当将真空电弧放电等离子涂层应用于型材复合材料制品（例如双涡轮叶片、独轮车叶片等）时，可能会出现确保涂层厚度公差的问题。本文介绍了所获得的涂层厚度不均匀性对叶片间通道的几何参数（其长度和宽度）的依赖性。我们开发了一个模拟模型，用于计算具有阴影区域的型材复合材料零件的真空电弧放电等离子涂层的厚度分布。
