Wear Characteristics on the can Opener of SUS 420J2

Abstract

Tinplate containers with high strength, good formability and corrosion resistance, has been widely used in food, beverages, grease, chemicals and other applications. In recent years, because of the significantly progress of tinplate container manufacturing technology, many tinplate cans have been opened in easy-open rings. However, a large number of food cans still use can openers as an important tool for opening cans. At present, in addition to the general traditional can opener is a single-edged knife in a lever manner, the other like roller, serrated or electric are driven by a gear wheel to rotate around the can to achieve the purpose of opening the can. Moreover, the wheel materials mainly are made from the stainless steels. To investigate wear characteristics on the can opener of the stainless steel of SUS 420J2, the experiments were conducted by the self-developed friction tester and its measure system in this study. According to the results, the effects of contact stress and sliding speeds on the wear of cutlery of the openers can be clarified.
