Preset layer thickness and laser scanning speed have definitive matching relation to the content of amorphous in the coatings, respectively;
预置涂层厚度及扫描速度分别与涂层中非晶含量存在着一定的匹配关系;
When the laser scanning speed increases, the laser radiation and cooling time get shorter, so the growing direction of microstructures is changed sharply.
提高激光扫描速率,造成激光辐射和冷却时间变短,合金微观组织生长方向变化显着;
Under the conditions of other technological parameters unchanged, the microstructure of the coatings becomes smaller and more homogeneous with laser scanning speed increasing.
在其他工艺参数不变的条件下,随扫描速度的增大,熔覆层组织变得细小、均匀;
The martensitic and undissolved carbide contents continuously increase as the laser scanning speed increases while the residual austenite decreases.
随激光扫描速度增大,试样中的马氏体和未溶碳化物的含量不断增加,残余奥氏体含量则连续下降。
