摘要

量热研究表明，电沉积制备的Ni-37 wt. %W纳米晶涂层在1000°C的温度下不会发生相变。激光加工影响涂层的性能，并且在所选择的模式下导致涂层中显着的晶粒生长，而不影响其化学成分。当能量输入一定时，涂层的显微硬度显著提高。

Strengthening of A Ni–W coating by laser processing

Calorimetric studies show that the nanocrystalline coating Ni–37 wt. %W produced by electrodeposition does not undergo phase transformations up to a temperature of 1000°C. Laser processing affects the properties of coatings, and in the selected mode leads to a significant grain growth in the coating, without affecting its chemical composition. At a certain energy input, a notable increase in the microhardness of the coating was revealed.
