柴油机气缸套是在高温、高压、润滑条件差的情况下,承受摩擦和燃烧产物的化学腐蚀。因此,气缸套的材料应具有较高的强度和耐磨性能。气缸套质量的优劣,直接影响柴油机功率的发挥和柴油机的大修寿命。所以,如何提高气缸套的使用寿命,是制造、使用和修理部门极为关切的问题。下面介绍我厂在中磷钒钛铸铁中加硼的试验,及其提高气缸套耐磨性的情况。 Diesel cylinder liner is in high temperature, high pressure, poor lubrication conditions, to withstand friction and chemical products of combustion. Therefore, the material of the cylinder liner should have high strength and wear resistance. The quality of the cylinder liner, a direct impact on diesel engine power and diesel overhaul life. Therefore, how to improve the service life of the cylinder liner is a matter of great concern to the manufacturing, service and repair departments. The following describes our plant in the phosphorus phosphorus vanadium titanium cast iron boron test, and to improve the wear resistance of the cylinder liner.
