Ni—Cr—B—Si系合金激光熔覆——激光覆层的组织及性能

A Study on Laser Cladding Ni-Cr-B-Si Alloys-Structure and Property of Coating Layer

较系统的研究了Ni—Cr—B—Si系合金的激光熔覆层的组织及性能,并相应地探讨了合金粉末预沉积方式和熔覆工艺参数的影响。

In this paper,the microstructure and property of Ni-Cr-B-Si alloy coating layer are described,the influence of pre-diposition processing of the alloy powder and laser cladding parameter on them are also discussed.
