[Problem-Solving Case] Wear Resistance Measures for Aluminum Cylinders

Coating only the inner diameter is necessary! A case where masking was performed for appearance reasons.

We would like to introduce a case that solved the issue of "the material was changed to aluminum for lightweight purposes, but the wear amount is greater than that of iron." The outer diameter could not be modified visually, so no treatment was possible. Therefore, both the inner and outer diameters remained anodized in color, ensuring wear resistance on the inner diameter. By applying the wear-resistant coating MD1900 only to the inner diameter, we improved low friction and wear resistance. The strength of aluminum was also secured with a treatment below 200°C. 【Key Points of Problem Solving】 - For areas that cannot be functionally treated with standard plating or coating, masking is performed. - In this case, masking was done for treatment due to visual reasons. - We selected the most suitable treatment from numerous surface treatment coatings, satisfying both appearance and functionality. *For more details, please refer to the PDF document or feel free to contact us.
