摘要

本研究的目的是研究激光功率对激光沉积17-4PH不锈钢硬度和耐磨性能的影响。用Zwick/Roell显微硬度计对硬度进行了研究，并用球盘式Anton Paar摩擦计磨损试验机对其耐磨性能进行了测试。研究表明，观察到平均硬度值和磨损行为的不规则增加和减少。这可能归因于铜沉淀的存在，由于在后续和之前的轨道层之间发生的再加热活动，铜沉淀在重叠区域更加集中。

Influence of Laser Power on the Microhardness and Wear Resistance Properties of Laser Metal Deposited 17-4 PH Stainless Steel

This aim of this research is to investigate the impact of laser power on the hardness and the wear resistance properties of laser metal deposited 17-4 PH stainless steel. Hardness was studied using the Zwick/Roell microhardness tester and the wear resistance property was carried out using the ball-on-disc Anton Paar-tribometer wear tester. The study revealed that an irregular increase and decrease in the average hardness value and wear behaviour were observed. This could be attributed to the presence of copper precipitate which was more concentrate at the overlapping region because of the reheating activity that is happening between the succeeding and preceding track layers.
