矿山机械的使用效果,在很大程度上取决于其工作的可靠性,与此同时,提高机械另部件的耐磨性也是很重要的。 为了完成第十一个五年计划的煤炭产量,在增加矿山机械产量的同时,还必须延长其工作寿命,而寿命在很大程度上又取决于所采用的防腐保护层的质量。 每年所使用的金属约有1/3遭到腐蚀。因腐蚀所造成的直接损失可由遭到腐蚀金属本身的造价和因个别另部件的腐蚀而使工作 The use of mining machinery, to a large extent depends on the reliability of its work, at the same time, improve the wear resistance of other parts of the machine is also very important. In order to complete the coal production in the 11th Five-Year Plan, while increasing the output of mining machinery, it is also necessary to extend its working life, which, to a large extent, depends on the quality of the anti-corrosion protection layer used. About a third of the metal used each year is corroded. The direct loss due to corrosion can be caused by the cost of corrosion of the metal itself and due to the corrosion of individual parts make work
