A multilayered corrosion and anti-galling coating for threads and wearable materials is a liner that can be superimposed onto the surface of a device in order to protect the surface from environmental hazards. To accomplish this, the coating has a base adhesive layer, an intermediary insulation ...
The 225W–TiN coating exhibits high aluminum adhering resistance.The surface roughness has a crucial influence on the galling properties of a coating.Surface roughness and metal compatibility are major factors affecting adhering resistance.The cups ironed by the 225W–TiN coated die were superior than ...
Thus, we have provided a method of manufacturing a zinc-based coated steel sheet with a zinc phosphate-film, having the steps of: applying a zinc-based coating to the surface of a steel sheet; applying water containing zinc phosphate particles to the surface of the zinc-based coating layer;...
