Kashima Coat Features
Outstanding Wear Resistance
- Proprietary technology electrolytically infuses hard anodized pores with molybdenum disulfide.
- Because the lubricant exists within the film — not on the surface — lubricity and wear resistance are maintained for the entire life of the anodic film.
- The synergy of hardness and lubricity delivers 3–5x the durability of standard hard anodizing.
- Proven self-lubrication excels in harsh, oil-free sliding environments.
High-Hardness Anodic Film
- A ceramic-hard anodic film reaching HV400 — dispelling the notion that aluminum is soft.
- Tens of billions to 70 billion micro-pores per cm² form within the hard anodic film.
- The film's hardness improves scratch resistance of aluminum parts, protecting components in high-torque, heavy-load environments.
- Steel-like wear resistance combined with the lightweight benefits of aluminum.
Extremely Low Coefficient of Friction
- Oil-free low friction achieved via integrated solid molybdenum lubricants.
- Reduces friction by 50–70%, preventing stick-slip, galling, and seizure.
- Thermal stability makes it ideal for high-performance engine components.
- Post-treatment polishing and lapping are possible, ensuring the finishing precision required for high-accuracy sliding parts.

Kashima Coat FAQs
-
Q1:How does Kashima Coat compare to standard hard anodizing or hard chrome plating?
The greatest strength is the simultaneous achievement of "hardness" and "lubricity." Our unique technology deeply fills the pores of an HV400 hard film with molybdenum disulfide, achieving 3–5x the wear resistance of hard anodizing and ultra-low friction (1/2–1/3 coefficient).
-
Q2:How does your molybdenum disulfide infusion method differ from other companies' lubrication treatments?
While other companies' lubrication treatments "apply" lubricants onto the film surface, Kashima Coat electrolytically "deposits and fills" molybdenum disulfide into countless micro-pores. This ensures that even if the surface lubricant is worn away, lubricating components are continuously supplied from within the film. Lubricity is maintained as long as the film exists.
-
Q3:What aluminum materials can it be applied to? Is it compatible with die casting?
It is applicable to major aluminum alloys such as A5052, A6061, and A6063. We especially recommend it for ADC12 (A380 equivalent), a die-cast aluminum alloy that is generally considered difficult to anodize. Please refer to the downloadable "Aluminum Material Properties Table" for film thickness limits and characteristics by alloy.
-
Q4:What is the standard lead time? How do international orders proceed?
Standard lead time is approximately 2 weeks. As Kashima Coat is a contract processing service, we recommend starting with a small-lot prototype for verification before moving to mass production. For international orders, we provide technical consultations that consider shipping costs and lead times.
-
Q5:What parts and applications is Kashima Coat most commonly used for?
It is widely used for sliding parts requiring high lubricity and wear resistance. We have extensive experience in automotive parts (valves, pumps), motorcycle parts (front suspensions), and outboard motor components. It is also used in manufacturing equipment and medical devices where smooth movement is required in clean environments.
