|Outline of plating|
|Hardening||Hard chromium plating||○||This is the hardest type among electric plating, and it excels in "abrasion resistance" and "corrosion resistance."|
|Electroless nickel||○||Since the plating is formed with a uniform film thickness, it is suited to "objects with complex shapes" and "objects with dimensional precision." Hv700 and higher can be provided.|
|Hard alumite||○||This process adds functional properties such as corrosion protection and decoration by oxidizing the surface layer of aluminum by electrolysis. Hv300 to 500 is available.|
|Improvement in sliding properties||Teflon electroless nickel||○||Plating film is uniform with good sliding properties as well as water repellency.|
|Teflon alumite||×||Delivers good sliding properties, peeling properties from other materials, and water repellency.|
|Delustering||Chemical pearskin||○||The surface roughness of the base is chemically increased. It addresses finer roughness than blasting.|
|Blasting||△||The surface roughness of the base is increased by blasting particles of iron, sand, glass and so forth in this method. There are wet and dry types.|
|Giving luster||Electrolytic polishing||○||A method which addresses a smooth, glossy surface by anodic dissolution of the metal surface in a certain solution|
|Chemical polishing||○||A method which chemically addresses a smooth, glossy surface by soaking the metal surface in a certain solution|
|Buffing||○||A method to mechanically polish the metal surface|
|Darkening||Blackening||△||It darkens the surface of iron and stainless steel materials in a simplified manner but it is inferior to other methods in corrosion resistance.|
|Black alumite||○||Used for aluminum materials.|
|Black chromate||○||Used for galvanized materials.|
|Black chromium||△||Used for materials that need to be black and hard.|
|Black electroless nickel||○||The material can be blackened with high dimensional precision.|
|Strict observation of dimensional precision||Electroless nickel||○||This is a process which satisfies both dimensional precision and corrosion resistance.|
|Chemical polishing||○||Used for burr removal and addressing finish tolerance.|
