Metal Surface Modification

About our diffusion treatment

Anti-exfoliation tough surface modification – our diffusion technology

Our surface modification treatment forms an alloy layer of extremely excellent adhesion, which is superior in high-temperature oxidation resistance, corrosion resistance, and abrasion (erosion) resistance, on the surface of material without degrading almost mechanical property of metal material.

We believe customers can achieve product life extension, productivity improvement, and cost reduction by this alloy layer.
