摘要
为了研究工艺参数对H13钢表面激光熔覆高熵合金成型和性能的影响,通过在H13钢表面激光熔覆Co_(1.5)CrFeNi_(1.5)Ti_(0.75)高熵合金,并分析了不同激光功率和扫描速度参数下熔覆层的形貌、相组成、硬度和耐磨性。研究表明,高熵合金Co_(1.5)CrFeNi_(1.5)Ti_(0.75)熔覆层为BCC相和FCC相;当激光功率为200 W、扫描速度为300 mm/min时,熔覆层成形良好,平均硬度最高,耐磨性能也最好。相关结果为提高H13钢的表面性能提供了有效、可实施的方法和试验依据。
In order to study the effect of process parameters on the forming and properties of laser cladding high entropy alloy on the surface of H13 steel,Co_(1.5)CrFeNi_(1.5)Ti_(0.75) cladding high entropy alloy was deposited on the surface of H13 steel by laser,and the morphology,phase composition,hardness and abrasion resistance of the cladding layer under different laser power and scanning speed parameters were analyzed.The results show that the cladding layer of the high entropy alloy Co_(1.5)CrFeNi_(1.5)Ti_(0.75) is BCC phase and FCC phase.When the laser power is 200 W and the scanning speed is 300 mm/min,the cladding layer has good forming,the average hardness is the highest,and the abrasion resistance is also the best.The relevant results provide an effective and practical method and test basis for improving the surface properties of H13 steel.
