The wear forms of friction materials at low temperatures are mostly adhesive wear and abrasive wear.
Metal components in the composite friction materials, such as iron and steel fiber, when they contact directly, and slide under certain pressures, the atoms of iron on the friction interface between the iron and steel fiber are easy to adhere; the adhesive points have been cut and adhered repeatedly, they are likely to form abrasive dust and break off, so that minute steel fibers are to be pulled out or partially torn, and cast iron materials may also be adhered or torn, therefore, resulting in wear and the Number of samples Sample size [mm] Total area of the test [cm 2 ] Dual-rotation Test pressure [Mpa] Temperature range [℃] Drum (disc) speed [r/min] Friction line speed [m/s] 2 25×25 12.5 Plane friction disc 0.5 100~350 480 7 formation of abrasive dust.
Serious adhesive parts are usually with larger abrasive dust, at the same time, materials around the adhesive points are easily to be torn off and form massive loss, as shown in Fig. 3 (A).

In this paper, compare some methods and materials.
In such methods researchers heat some materials to 900 Celsius degrees and provide hydrogen and some other materials[7].
Researchers used sulfuric acid and some other materials like iodic salts in these studies.
Furthermore, water steam and other materials should be conducted toward given tanks.
- Water is also one of the most plentiful materials on the earth

Emphasis was placed on utilizing materials sourced locally.
