Although laser absorptivity of NiCoCrAlY powder was higher than that of NiCrBSi powder and thick NiCoCrAlY coating can be obtained,hardness of NiCrBSi coating containing several reinforcements was higher than that of NiCoCrAlY coating.

• 虽然NiCoCrAlY粉比NiCrBSi粉的激光吸收率高,可以得到较厚的涂层,但是含有多种硬质增强相的NiCrBSi涂层硬度高于NiCoCrAlY涂层。
