Guard rail and preparation method thereof
The invention aims at providing a guard rail and a preparation method of the guard rail. The guard rail is that carbide coatings are arranged on the surfaces of working part. The guard rail is characterized in that the carbide coatings are arranged at the working parts on the upper surface and the lower surface; a pseudo-single crystal TiC dense ceramic layer, a micron TiC ceramic layer and a TiC and base body combined layer are arranged in a gradient manner from outside to inside in a sequence and are applied to the surface of carbon steel. According to the guard rail and the preparation method of the guard rail, a base body and a titanium composite body are casted, an external carbon source is introduced, and the carbide coatings are formed on the surface of the base body by heating and heat preserving; the coatings and the base body are combined by a metallurgical manner, so that the combining force is high, the problem of poor combining force and easily-fallen particles due to non-metallurgical combination of hard particles and metal base material in the prior art can be overcome, and the wearable performance of the working surface of the guard rail can be greatly improved.
