采用先进的喷射沉积技术,研制一种高硅铝合金发动机缸套材料,并经过挤压加工、热处理、成形加工、摩擦学性能测试与摩擦学机制分析,最后在单缸机上装机试验。结果表明,高硅铝合金缸套材料具有良好的摩擦学性能,这归功于高硅铝合金中比钢、铸铁还硬的硬质点;在所测试的油耗、废气压力、磨损量以及排温等指标数据方面,比相应的铸铁缸套更具有优越性。 Using advanced spray deposition technology, a high silicon aluminum engine cylinder liner material was developed, and after extrusion processing, heat treatment, forming, tribological properties and tribology test analysis, and finally installed on a single cylinder machine test. The results show that the high silicon aluminum cylinder liner material has good tribological properties, which is attributed to the high-silicon aluminum than hard steel, cast iron hard points; in the test fuel consumption, exhaust pressure, wear and tear and row temperature And other indicators of data, more than the corresponding cast iron cylinder liner has more advantages.
