Service Detail from Miyaki USA, Inc.
Kashima Coat achieves new possibilities and is actively used in many mechanical fields.
For samples, along with the technical improvement of hydraulic equipment, carburized steel alloys are being replaced by machined aluminum alloys hard-anodized for the light-weight property of the material. At the same time, Kashima Coat has been tested and approved in the industry.
Manufactures of shock absorbers and suspensions for motorcycles continue to seek technical improvement with control stability and durability. Kashima Coat is being used on aluminum dampers as a state-of-the-art coating for lower friction, wear resistance, and its distinctive gold color appearance.
In automotive engine units, smooth piston movement without scuffing or wear under high temperatures is critical. Kashima Coat is used on piston head units and piston cylinder for better lubrication resulting in longer product life. Also, Kashima Coat is being used on arms lockers without bearing for weight and cost savings for the self-lubricity of the coating.
For any questions or inquiries of Kashima Coat technical information or production applications, please contact us by phone or send us an e-mail.
Conventional hard anodic film is normally porous and low to moderate wear resistance, and there are more chances of abrasion and wear, caused by failure of lubrication in higher pressure, vibration, and friction areas. Kashima Coat with lubricating property and higher resistance characteristics was researched and developed by Miyaki Co., to prevent such problems. Kashima Coat is a proprietary hard anodizing processing that Miyaki Company of Japan has invented, lubricating molybdenum disulfide deposited via electrical induction into the billions of micro-pores on the surface of hard-anodized aluminum for better lubrication and less abrasion and wear.
There are about 70 billion of anodic cells in 1 cm2with molybdenum disulfide deposit and penetrated into micro-pores from the bottom of each cell per right picture, and Kashima Coat improves on lubrication and corrosion resistance of conventional hard anodizing and other common types of coating such as Teflon, Graphite, and Tungsten disulfide.
We conduct research and development specializing in surface processing technologies for aluminum, such as Kashima Coat, hard anodized aluminum and ordinary anodized aluminum. We have earned a reputation in various fields for making high-quality products with a homogenous film.
Supporting our fantastic world
Aluminum - it goes without saying that “light weight” is its greatest characteristic. It is used in cars, motorcycles and bicycles, freight cars for railroads, etc. where it helps to increase speed and reduce energy expenditure and CO2 emissions through reduced weight.
Aluminum has many other characteristics such as strength and beauty, as well as superior recyclability and workability. Its range of application is continually expanding and includes: electrical machinery, industrial machinery, metal products, boats and ships, food packaging, daily necessities and civil engineering and construction materials. As a raw material, aluminum greatly contributes to modern society. Aluminum - a metal with great promise.
However, it is a little-known fact that the success of aluminum can be attributed to “surface treatment”.
At Miyaki, we take pride in carrying out surface treatments that suit the application of the aluminum to improve its superb characteristics and create new value. We place great importance on the continual improvement of our existing technical capabilities so that we can help our customers to advance or resolve problems. We are further pursuing technical research, including Kashima Coat - which was researched and developed independently by Miyaki - in order to contribute to the new world created by aluminum.
Original technology that combines the expertise of Miyaki
Kashima Coat is a lubricating anodized aluminum researched and developed by Miyaki. The tough film of hard anodized aluminum is enough to create high pressure at contact surfaces, and when used in places where small vibrations or rubbing occur, “scuffing” and “seizing” result. Kashima Coat was created to provide lubrication for hard anodized aluminum as well as improve its abrasion resistance.

Piston: Reducing Adhesion of Piston Ring to Ring Ditch and Wear Resistance, Wear Resistance of Piston Pin Hole
Pulley: Wear & Abrasion Resistance of Gear Tooth Ditch
Cylinder: Anti-Scuffing & Wear & Abrasion Resistance
Arms Locker: Shifting to Aluminum from Steel Wear & Abrasion Resistance
Valve Spool: Anti-Fretting,Improved Sliding Movement
Deposit crystallization of molybdenum disulfide improves on lubrication of hard anodized aluminum film in sliding or piston movement areas without lubricant.
Kashima Coat improves on corrosion resistance by 4~5 times of chromic surface.In salt spray test (5%35?) of Kashima Coat minimum 50µm thickness, no rust was detected even after 1,000 hours of its testing
Molybdenum disulfide improves on lubrication and sustains lower friction even at higher temperature of 300 Celsius (6 intervals of 10 min. heating) Kashima Coat can also prevent melting and scuffing in high-temperature automotive applications such as engine pistons.
Electrical breaking voltage of conventional hard anodizing is approx. 1 µm per 10 voltages, but Kashima Coat improves on electrical resistivity by 50% and erosion by overheating. Kashima Coat is suitable for insulating parts for computer applications as well.
Hardness of Kashima Coated (hard anodizing) aluminum can reach 400HV. On some abrasion resistance testing, Kashima Coat (hard anodizing) was measured 3 times harder than chrome plating. Kashima Coat on aluminum application is reviewed as an alternative component of steel or stainless steel for light-weighted and hardness characteristics in automotive applications.
Kashima Coat can be evenly coated throughout surface.
Aluminum has about one-third the density and stiffness of steel, and it is easily machined, cast, drawn and extruded. With Kashima Coat, there are more opportunities for the use of aluminum characteristics on more applications.
Depending types of aluminum and surface thickness, color of Kashima Coat may change, but the color can be from gold, brown, and dark brown.
