1. preparation optionally contains at least one kollag, the method of the polymer coating (5) that can grind off, this polymer coating is at metal gear teeth element (1, 2) tooth (7, 8) on surface, this polymer coating is used for regulating two engagement gear teeth elements (1, 2) tooth (7, 8) backlash (4) between, according to the method at least one gear teeth element (1, 2) in surperficial at least a portion of tooth (7), apply the polymer coating (5) that can grind off, it is characterized in that, applying polymer coating (5) before, surface to be coated is processed in plasma, and afterwards polymer coating (5) is applied directly on described surface,Wherein, the surface tension of the metal surface of gear teeth element (1,2) is compared surface tension before described processing and is improved at least 30%, or, use such gear teeth element, in region to be coated, its surface tension is 40mN/m at least.
