Technical Field
The invention belongs to the technical field of camshafts, and particularly relates to a high-strength wear-resistant camshaft.
Background
The camshaft is a component in a piston engine. Its function is to control the opening and closing action of the valve. Although the rotational speed of the camshaft is half of that of the crankshaft in a four-stroke engine (the rotational speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), the rotational speed is still high and the camshaft is subjected to a large torque, so that the camshaft is required to be high in strength and support in design, and the camshaft is generally made of high-quality alloy steel or alloy steel. Because the valve motion law is related to the power and the running characteristics of an engine, the camshaft design plays an important role in the design process of the engine.
Most of the existing cam shafts are integrally formed, and the surface of the existing cam shaft is generally plated with a layer of compact oxide film by adopting a conventional heat treatment method. The oxide film has certain corrosion and abrasion resistant effects, but the abrasion resistant effect is not good, so that the durability of the camshaft is not enhanced, and the cost is increased excessively.
Therefore, a camshaft with a high-strength wear-resistant coating is urgently needed.

The components are sieved after being ball-milled by a wet method, then mixed into absolute ethyl alcohol to be stirred and mixed, and finally sprayed to the surfaces of the exhaust cam and the air inlet cam to form a compact film layer, so that the wear resistance of the cam part is improved, and the service life is prolonged.
