α-processing
A unique air blasting technology "α-processing" is a surface treatment method that can provide various effects by forming a fine texture.
Features of α-processing |
Improvement of abrasion resistance, fatigue strength and slideability
A unique air blasting technology "α-processing" creates "Nano crystal" that is much finer than the crystal created by conventional fine particle shot peening. Hardness is improved by Nano-crystalizing the top most layer of the parts. And, "peening effect" applies residual compressive stress as well. And, "fine texture" formed by α-processing reduces the contact area so that sliding resistance is also reduced to improve slideability.
Improvement of slideability of coatedFine texture can be formed on coated surface to improve lideability of the surface leaving hard coating membrane such as DLC or chrome plating there. Processing can be performed without peeling off the coating.

No dulling on edges

Improvement of slideability of high strength and highly brittle material
Fine texture can be formed on high strength and highly brittle material such as zirconia or cemented carbide to provide high slideability.
Example |
Various effects such as functionality improvement of sliding parts, longer service life and better releasing property of mold dies, longer service life of tools, etc.
|
|
Precision drive parts● Durability of precision drive parts is more than fivefold improved ● Improved slideability of sliding parts |
|
|
Precision press die and punch● Durability of forming dies can be more than tenfold improved ● Releasing property of DLC coated forming punch for aluminum can be improved |
|
|
Plastic mold dies● Abrasion strength of sprue for fiber reinforced resin can be improved ● Durability of insert dies can be more than tenfold improved ● Less contamination on screws. Suppression of black spots due to carbides |
|
|
Rubber mold dies● Suppression of scratch or tear-off by improved releasing property ● Need for no releasing agent and better releasing property in molding medical devices |
|
|
Cutting tools● Durability is improved by more than 60% ● Suppression of built-up edge generation in cutting of hard-cut materials. Improvement of cut surface finish |
