Compound technology of titanium carbide reinforced cast iron base brake disc

Abstract

The invention provides a compound technology of a titanium carbide reinforced cast iron base brake disc. Titanium wire is weaved into a titanium wire mesh; the titanium wire mesh is coiled by one layer or multiple layers or overlaid into a titanium wire stereoscopic and netted skeleton which adapts to the shape of a brake disc; the stereoscopic and netted skeleton is pre-arranged in a brake disc cast; then liquid cast iron is poured into the cast and is filled in each gap of the stereoscopic and netted skeleton; after cooled, a titanium wire-cast iron binary material prefabricated body is obtained; the prefabricated body is put into a thermal treatment furnace and keeps temperature at carbide forming temperature; and the cast iron base brake disc of which the working surface is a titaniumcarbide reinforced cast iron compound layer is obtained. The invention has the effect on abrasion resistance and hard phase, gives full play to the favorable abrasion resistance of titanium carbide hard phase and good strength and toughness of cast iron, has convenient technology regulation and control and stable and reliable quality, and solves the problems of incomplete reaction of composite material, uneven wild phase particle distribution, weakened wild phase interface pollution and the like.

Description

technical field [0001] The invention relates to a preparation process of transport equipment parts, in particular to a compound process of titanium carbide reinforced cast iron-based brake discs, and belongs to the technical field of design and manufacture of transport equipment parts. Background technique [0002] The brake disc is an essential part of all vehicle braking systems. It is fixed on the axle and rotates with the wheel. When braking, the brake block is pressed onto the brake disc under the push of the caliper piston. Through the brake block and the The friction between the brake discs reduces the wheel speed to achieve the purpose of vehicle deceleration and braking. In this working condition, the brake disc will bear the pressure and friction of the brake block, and wear will occur in the relative movement with the brake block, especially when there are sand and other sundries on the working surface, the wear will be more serious. Therefore, the material for m...
