徴どづるもの【・ある。In view of the above, the present invention provides a surface treatment for aluminum material that can provide excellent surface lubrication properties as well as wear resistance.
The purpose is to provide two methods, and it is made by applying hard alumite treatment to aluminum material.
This is heated to produce many cracks in the coating on the aluminium 1, and then the coating surface is impregnated with a lubricant made of fluorine resin or silicone resin.

優れた皮膜である。The aluminum material is first treated with hard alumite 1 (hard anodic oxidation treatment) according to known conditions to form a microscopically porous hard alumite film (hard @divine anodization film) on its surface. . The coating itself has a high hardness of 300 or more in Vickers hardness, for example, and has excellent wear resistance.

ある。Therefore, next, the aluminum material subjected to the hard alumite treatment is heat treated at a predetermined temperature to create many cracks in the film of the hard alumite 1. This heating temperature is
It is selected appropriately depending on the use of the aluminum material, but in order to prevent many cracks from remaining in the form of grooves even after cooling, the temperature is usually about 200 to 250°C, particularly preferably 230°C. It is preferable to heat it to about .degree.

とができるものである。Therefore, next we will examine the aluminium 1 that has formed these many cracks.
- The film is impregnated with a lubricant made of a fluororesin or silicone resin with excellent lubrication properties, and this is fixed in the holes or grooves of the hard alumite film including the cracked parts. This impregnation and fixation is done in advance with aluminium 1.
By applying a dispersion or solution of the lubricant by rubbing it onto the surface of the hard alumite film in a state where ~ has been cooled to, for example, -20°C, and then wiping off the excess lubricant after returning it to room temperature ( It is advantageous to cool the aluminum material, impregnate it with the lubricant, and then return it to room temperature and perform a post-heat treatment of 7 m-1, so that the lubricant is applied to the aluminum film. Due to its relatively small coefficient of thermal expansion, it can be tightly fixed and covered in a comb.

うるちのとなしうる。Therefore, the aluminum material subjected to the surface treatment according to the present invention has a hard alumite skin fi! r!
In addition to the wear resistance, the lubricant occupies a relatively large surface area and is firmly adhered to the surface, which further increases the wear resistance and has excellent lubricity. It is suitable for use in applications requiring good wear resistance.
