Abstract: To solve the problem that the selection of surface coating alternative mainly considers technical and economic issues,a low-carbon oriented comprehensive evaluation method for surface coating alternatives of parts and components was proposed.Incorporating low-carbon index,a comprehensive evaluation index system for surface coating alternatives of parts and components was established covering technical feasibility,economics,green and low-carbon,and coating performance.In addition,the quantification methods of each indicator were determined.Since the single weighting method has a certain bias,the Analytic Network Process(ANP)and CRITIC methods were used to determine the subjective and objective weights of each indicator,and minimum relative information entropy was used to calculation the combined subjective and objective weights.Vise Kriterijumski Optimizacioni Racun(VIKOR)method with improved gray correlation was used for comprehensive evaluation of surface coating alternatives,and the optimal surface coating alternative was determined by ranking the superior and inferior solutions.The surface hardening of plunger parts of a pump plant was used as an example to verify the feasibility and effectiveness of the proposed method and to provide reference for the evaluation and selection of surface coating alternatives for various parts.

Key words: low-carbon, surface coating, portfolio weights, comprehensive evaluation

摘要： 针对目前零部件表面涂层方案选择主要考虑技术性、经济性的问题,提出一种面向低碳的零部件表面涂层方案综合评价方法。融入绿色低碳指标,构建涵盖技术可行性、经济性、绿色低碳、改性性能等因素的零部件表面涂层方案综合评价指标体系,并确定各个指标的量化方法;针对单一赋权法具有一定偏向性的问题,利用网络层次分析法(ANP)和CRITIC法分别确定准则层各指标的主观权重与客观权重,并利用最小相对信息熵获得主客观组合权重;采用灰色关联改进的多准则妥协解排序法(VIKOR)对表面改性方案进行综合评价,通过优劣解排序确定最佳表面涂层方案。以某水泵厂柱塞零部件的表面硬化为例,验证了所提出方法的可行性和有效性,为各类零部件表面涂层方案评价及选择提供参考。
