Improvement of Surface Texture of Stainless Steel by Utilizing Dry Blasting - 3rd Report: Effect of Blasted Texture on Adhesion of Plating -

Abstract

Recently, wet blasting is generally used such as liquid honing and water jet machining in surface before plating of stainless steel. The outstanding feature of wet blasting is to prevent generation of static electric charge, to use micro abrasive grain, and to have cushioning for workpiece. On the other hand, the disadvantage of wet blasting is to generate corrosion of equipment and liquid waste under processing. Moreover, the using abrasive grain is available on a limited basis. In particular, improvement disposal of liquid waste under processing is crucial in the near future. This paper makes proposal for improvement of surface texture by utilizing dry blasting, and it conducts improvement of surface texture about martensite stainless steel (SUS420J2 In JIS), which is used in material for scale. In the previous report, it has been cleared that relationship between surface texture and wettability. In this report, adhesion of plating was measured by scratch test. As a result, it was cleared that availability of adhesion evaluation by utilizing wettability.

Areal Surface Texture Parameters for Copper/Glass Plating Adhesion Characteristics

“…Surface roughness average (arithmetical mean deviation) (Ra) is a familiar profile parameter and has previously been used to characterize the effect of substrate surface roughness and coating thickness on the adhesion behavior of TiN film deposited on steel substrates [7], as well as being employed to define a linear relationship with average cleavage strength, which was also a function of linear profile length Rlo [8]. Existing work has also investigated the relationships between adhesive strength, surface texture and wettability for plating martensitic stainless steel for adhesion, concluding that Journal homepage: https://content.sciendo.com (understandably) wettability was improved and adhesive strength increased when surface roughness Ra increased [9], [10]. However, additional 2D parameters have also been nominated as being of potential use when trying to understand issues of plating adhesion and bond strength.…”
