二次旋转组合设计在零件修复试验中的应用

Application of the design of rotation-regression-orthogonal combination on the restoration experiment of the parts

采用二次旋转组合设计的方法进行零件修复试验,并以45钢和球墨铸铁为基材的零件镀铁修复为例,介绍二次旋转组合设计在零件修复中的具体应用,建立镀层结合强度与活化电流密度、活化时间之间的数学模型.结果表明,该方法具有试验次数少、便于分析和应用.

The experiment for the restoration of the parts was carried out with the design of the rotation-regression-orthogonal combination,and the experiment is the iron-plate restoration of the parts based on 45# carbon steel and ductile iron as example.Through the method,the mathematical models depicting the changing relationship between the adhesion strength with the activation current density and the time.The result showed that the rotation-regression-orthogonal-combination design was available to reduce the experimental times and facilitate the analysis and application.
