发动机的寿命在很大程度上决定于气缸套—活塞组零件的耐磨性,首先是气缸套的耐磨性。非合金铸铁气缸套不能保证发动机必要的寿命,尤其是当它们在磨料磨损过程加剧或摩擦表面热作用增加的恶劣使用条件下工作时更是如此。镶入高镍奥氏体铸铁的尼莱吉斯特镶块以提高气缸套的耐磨性,虽然会明显增加气缸套—活塞组的寿命,但也会出现一系列不利于摩擦付工作的因素。实验室的试验和生产实际应用的结果表明,合金灰铸铁气缸套具有最好的耐磨性。TAЗ柴油机带有散热片的气缸套就是用低合金灰铸铁制造的。
The life of an engine depends to a large extent on the wear resistance of the cylinder liner-piston assembly components, above all the wear resistance of the cylinder liner. Non-alloyed cast iron cylinder liners do not guarantee the necessary life of the engine, especially when they are operated under harsh conditions of use where abrasion wear is aggravated or frictional surface heat is increased. Nilagist inserts with high-nickel austenitic cast iron improve the wear resistance of cylinder liners, although they significantly increase the life of the cylinder liner-piston set, but there are also a number of factors that are detrimental to frictional work . Laboratory tests and production The results of the practical application show that the alloy gray cast iron cylinder liner has the best wear resistance. The TAZS diesel engine liner with heat sink is made of low-alloy gray cast iron.
