摘要
本文对激光熔覆用WF—218合金粉末的激光熔覆工艺和熔覆层组织、性能进行了研究,获得了WF—218钴基合金粉末激光熔覆层厚度和宽度与最小比能量关系曲线和熔覆层的性能数据,为用户选择和使用激光熔覆WF—218合金粉末和在气门等产品上应用提供了依据。
Through studying the technology of laser cladding WF218 alloy powder and the properties and micro-structure of the alloy fabricated by laser cladding ,it is obtained that minimum energy density curve changed with the thickness and the widthness of the alloy fabricated by laser cladding and the property of the alloy fabricated by laser cladding . The data is on basis of the users choosing and supplying WF218 alloy powder by laser cladding and the alloy fabricated by laser cladding in the valve .
