秋田化学工業 List of Products and Services

This refers to a process for removing welding discoloration from stainless steel and achieving a gray or matte surface. The treatment also slightly improves corrosion resistance.

• Surface treatment contract service

The surface of metals exhibits various roughness due to the influences of their manufacturing processes and mechanical treatments such as machining. For device components made from these metals, a low surface roughness and a shiny appearance are required for their intended purposes. Until now, mechanical polishing (such as buff polishing) has been used to achieve this goal. However, for complex shapes and in precision components where dirt and debris are undesirable, mechanical polishing has become inadequate. Therefore, the process of immersing metals in a solution and utilizing electrical power for polishing, known as electrochemical polishing, has gained attention. In precision component devices, especially those related to semiconductors, many parts undergo this electrochemical polishing.

• Wafer processing/polishing equipment

It generates an oxide film on the surface of stainless steel.

• Plating Equipment

It is a treatment that does not contain chromium ions, serving as an alternative to hexavalent chromium type chromate.

• Plating Equipment

For the purpose of aluminum corrosion prevention, when the product is used as an anode and electrolyzed in an electrolyte solution, a thick oxide film is formed on the surface.

• Plating Equipment

Electroless nickel is an alloy with phosphorus and, along with electroplated nickel, forms a nickel-based coating. When the purpose is rust prevention, there is hardly any difference between the two. However, electroless nickel covers the product regardless of its shape, resulting in superior corrosion resistance compared to electroplating.

• Plating Equipment

It is widely used as a representative rust prevention treatment in various fields. In particular, in addition to being extremely effective for the corrosion protection of iron, advancements in plating baths and chromate treatments have also improved appearance performance.

• Plating Equipment

This is an environmentally friendly deep black plating that does not contain hexavalent chromium in the plating film, like zinc-plated black chromate, nor does it use hexavalent chromium during the process, like black chrome plating.
