摘要

钢（AISI 1078）连杆上的涂层可用于减少摩擦，提高耐磨性，以提高耐久性。在本研究中，研究了未涂层、蒸汽涂层和磷酸锰涂层钢（AISI 1078）试样的摩擦学行为。磨损试验是通过使用以1.6的恒定速度运行的销-盘装置进行的在9.8至49的正常负载下m/s 室温下为N。通过增加施加的载荷，观察到磨损率的增加。然而，蒸汽涂层试样在低载荷和高载荷下都比所有其他试样表现出更好的耐磨性。为了更好地了解所涉及的磨损机制，在扫描电子显微镜下对磨损表面和收集的碎屑进行了分析，指出在试样的磨损测试过程中，既涉及粘合机制，也涉及研磨机制。图形摘要

Dry sliding wear behaviour of steel (AISI 1078) after coating with steam treatment and manganese phosphating

ABSTRACT Coating on a connecting rod of steel (AISI 1078) may be used to reduce the friction and improve the wear resistance to enhance the durability. In this study, the tribological behaviour of uncoated, steam-coated and manganese phosphate-coated steel (AISI 1078) specimens was investigated. Wear tests were carried out by using a pin on disc apparatus operating at a constant velocity of 1.6 m/s under the normal load from 9.8 to 49 N at room temperature. Increment in wear rate was observed by increasing the applied load. However, steam-coated specimen shows better wear resistance than all other specimens at both low and high loads. For a better understanding of the involved wear mechanism, worn surfaces and collected debris were analysed under a scanning electron microscope, which point out that both adhesive and abrasive mechanism were involved during wear testing of specimens.
