Abstract

The invention discloses abrasion-resistant and friction-reducing emulsion. The abrasion-resistant and friction-reducing emulsion comprises 50 to 69 parts of polytetrafluoroethylene emulsion, 2.0 to 5.9 parts of chromium oxide, 2.5 to 5.4 parts of phosphoric acid, 0.2 to 0.4 part of lauryl sodium sulfate, 0.5 to 3.0 parts of abrasion-resistant additive and 20 to 40 parts of distilled water. The invention also relates to a preparation method for spraying the abrasion-resistant and friction-reducing emulsion on the surface of a soft metal. The method comprises the following steps of: preparing the abrasion-resistant and friction-reducing emulsion with the components; treating the surface of soft metal matrix; spraying the emulsion on the surface of the soft metal; drying the soft metal; sintering the soft metal; and quenching the soft metal. When the abrasion-resistant and friction-reducing emulsion of the technical scheme of the invention is coated on the surface of the soft metal, the friction coefficient can be reduced by 20 percent, and the abrasion amount ratio of the soft metal to the basis material is less than or equal to 0.5. The abrasion-resistant and friction-reducing emulsion can be widely used for surface treatment of the soft metal such as copper, aluminum and alloy thereof and the like at a friction and abrasion part of a gear pump side plate, a bearing bush, a bearing block hole, a cylinder barrel and the like, and has novel structure and originality.

Description

technical field [0001] The present invention relates to a wear-resistant and anti-friction emulsion, and also relates to a preparation method for spraying the wear-resistant and anti-friction emulsion on a metal surface, in particular to a kind of soft material with low hardness and good yield and compliance. A method for preparing a wear-resistant and anti-friction coating on a metal surface. Background technique [0002] Copper, aluminum and their alloys, as well as low-hardness metals or alloy materials (soft metals) such as low-carbon steel and low-alloy steel (soft metals) have good running-in performance and reducing friction between friction fittings due to their good concession and compliance. friction performance. Therefore, this kind of soft metal is often used in conjunction with tempered or quenched steel parts, and is widely used in moving friction parts, such as gear pump side plates, bearing bushes, bearing housing holes, cylinders, etc. However, due to the ...
