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.
Conventional coating tools have a high affinity for ductile materials, like aluminum alloy,
so cutting chips tend to adhere to cutting edge and work material surface. Therefore, chipping is
caused, and surface texture is degraded. In order to solve these problems, recently, DLC
(Diamond-Like-Carbon) has been applied to coating material. In this research, it is curried out
cutting of Aluminum alloy by the use of DLC coating tool, and examined influence of DLC coating
conditions on cutting characteristics. So far we have been concerned with the effect of type of
hydrocarbon gas (acethylene:C2H2, methane:CH4) on cutting. As a result, it is revealed that
cohesion of chips decreases, and surface roughness of work material improves in the case of
acethylene-DLC. On the other hand, internal stress is produced by deference in hardness between
tool surface and DLC film, and which is considered cause of film peeling [1]. Therefore, we
examined interlayer between DLC film and tool surface in order to relax of internal stress. As a
result, it was cleared that Titanium interlayer excels in adhesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
