不锈钢耐蚀装饰膜的性能检测

PERFORMANCE EVALUATION TECHNIQUES OF FILM AND COATING ON STAINLESS STEEL

综述了检测不锈钢耐蚀装饰膜层的各种性能的方法。首先介绍有关的国标、ASTM和DIN标准,然后讨论已有的各种测试和评价方法相互之间及与标准的差异。分析了侵蚀性介质在性能评价中的作用。提出了新的测试方法和评价方案。

The performance evaluation techniques of coating and film on stainless steel are reviewed. The film and coating on stainless steel covered in this paper are colored film prepared by either by electrochemically or chemically, passive film after polishing and cleaning, thermal barrier and ceramic coating and so on. Detail discussion of each technique is focused on the suitability, reliability and performance indicator（s） an evaluation process could generate. Additional performance indicator if available and not mentioned in previous researches is also suggested by authors with an intension to extend the existed technique and generate more performance information. At the end of each category, the applicable ISO, ASTM, DIN and GB standards are discussed and compared for encouragement of the possible adoption of standards.
