一种新型电弧喷涂气缸套的工业化应用及质量检测方法

近年来,随着全球变暖问题日趋严重,各大汽车制造商正在采用各类技术减少发动机油耗及尾气排放。作为减少发动机重量、增强发动机缸体内壁耐磨性能、减少摩擦力的新技术,气缸套热喷涂沉积技术成为了节能减排的重要技术手段。文章首先介绍了气缸套热喷涂技术的原理、加工工序以及几种常用的热喷涂沉积技术,而后引出了对一种新型电弧喷涂气缸套的工业化应用的介绍,进而重点阐述了某品牌汽车发动机制造厂商技术人员对新型电弧喷涂气缸套的质量检测方法。

Industrial Application and Quality Detection Method of Novel arc Spraying Cylinder Liner

In recent years,with the global warming problem becoming more and more serious,some major automobile manufacturers are using various technologies to reduce engine fuel consumption and exhaust emissions.As a new technology to reduce the engine weight and enhance the wear resistance of the inner wall of the engine block and reduce the friction,the cylinder liner thermal spray deposition technology has become an important technology to save energy and reduce emission.This thesis firstly introduces the principle,procedure and several commonly used thermal spray deposition technologies of cylinder liner,then introduces the industrial application of a new type of electric arc spray cylinder liner,and then focuses on the quality inspection method of a brand of automobile engine manufacturer’s technicians for the new type of electric arc spray cylinder liner.
