摘要:
为了解决低熔点材料电弧熔射成形模具使用性能差、寿命低等问题,提出电弧熔射成形制作不锈钢模具的方法.以不锈钢材料为研究对象,研究电弧熔射过程中输入参数对飞行熔滴温度和速度的影响,分析熔滴的扁平化过程,并对熔射层的硬度和孔隙率进行测试.实验结果分析表明,雾化气体压力直接影响熔滴的雾化状态,熔滴飞行温度、速度,以及成形质量.随着空气压力的增大,熔滴飞行速度提高,熔射层致密且氧化物质量分数减少,气孔率降低,显微硬度也大大提高.熔射模的预热温度直接影响着熔滴的扁平化状态,从而影响熔射成形质量.
Abstract:
To solve the problem of short service life and poor performance of low melting point alloy mould manufactured by arc spray forming,the manufacturing of stainless steel mould has been presented.With stainless steel as the research object,the influence of the inputting parameters on the temperature and speed of flying droplets during spraying is investigated,the flattening process of the droplets is analyzed,and the hardness and porosity of the coating is measured.The experimental results have indicated that the air pressure has direct influence on the atomization,in-flight temperature,speed,forming quality of the droplets..With the increase of air pressure,the flying speed of droplets increases,the coating becomes denser,the mass percentage of the oxide and the porosity of the coating decreases,and the micro hardness increases significantly.It has also revealed that the preheating temperature of the prototype has direct influence on the flattening states,and also on the forming quality consequently.
