将ZM5镁合金置入铝、锌混合粉末中,在氩气保护下,于温度(390±5)°C保温8h进行表面固态扩渗合金化处理。研究表面固态扩渗合金化处理前和处理后ZM5镁合金在两种不同冲蚀磨损环境中(油和石英砂,水和石英砂)的冲蚀磨损行为。结果表明:当冲蚀磨损介质为油和石英砂时,冲蚀磨损表面形貌为切削沟痕。油对试样的腐蚀很弱,切削磨损是主要的磨损机制。当冲蚀介质为水和石英砂时,冲蚀磨损试样表面为腐蚀坑和裂纹。水的腐蚀和石英砂的冲刷作用加剧试样的磨损质量损失。在相同的冲蚀介质中,经过表面固态扩渗合金化处理的试样的耐冲蚀磨损性能均比未经过表面固态扩渗合金化处理的试样好。
ZM5 magnesium alloy into aluminum, zinc mixed powder, under argon protection, at a temperature of (390 ± 5) ° C for 8h surface solid state alloying treatment. The erosive wear behavior of ZM5 magnesium alloy before and after solid-state alloying treatment was studied in two different erosive environments (oil and quartz sand, water and quartz sand). The results show that when the erosion media is oil and quartz sand, the surface morphology of the erosion wear is notch ditch. Corrosion of oil on the sample is weak, cutting wear is the main wear mechanism. When the erosion medium is water and quartz sand, erosion and erosion of the specimen surface corrosion pits and cracks. The corrosion of water and the erosion of quartz sand aggravate the loss of wear quality of the specimen. In the same erosion medium, the wear resistance of the specimens after alloying by surface solid-state alloying is better than those without the surface solid-state alloying treatment.
