工艺参数对钛合金激光沉积成形质量影响的研究

Research on Process Parameters of Laser Metal Deposition Quality Influence

在激光沉积成形中,为了保证试件的成形质量,其关键因素是找出相互匹配的工艺参数。利用多组对比试验,通过分别改变激光功率、扫描速度、送粉速率和扫描间距来探究工艺参数对沉积表面成形质量的影响规律,并根据规律总结出工艺参数与粉末熔化率的关系公式,推算出了一系列相互匹配的工艺参数。

In laser mental deposition, in order to ensure the forming quality of specimens,the key factor is to find mutual matching process parameters.Using many groups of contrast test, influence law that the process parameters on the of deposition surface forming quality is inquired by changing respectively laser power, scanning speed, send powder rate and the scanning interval. According to the law, the process parameters and powder melting rate relationship formula is summed up. And a series of mutual matching process parameters is calculated.
