How Are Car Carbide Anti-skid Spikes Prepared?

The preparation process of car carbide anti-skid spikes can be divided into four basic stages:

1. Removal of forming agent and pre-sintering stage

In this stage, the sintered body undergoes the following changes: the removal of the forming agent, as the temperature rises at the beginning of sintering, the forming agent gradually decomposes or vaporizes and is removed from the sintered body. At the same time, the forming agent more or less adds carbon to the sintered body, and the amount of carbon addition will vary with the type, quantity and sintering process of the forming agent. The oxides on the surface of the powder are reduced. At the sintering temperature, hydrogen can reduce the oxides of cobalt and tungsten. If the forming agent is removed and sintered in vacuum, the carbon-oxygen reaction is not strong. The contact stress between the powder particles is gradually eliminated, the bonding metal powder begins to recover and recrystallize, surface diffusion begins to occur, and the strength of the compact is improved.

2. Solid phase sintering stage

At the temperature before the liquid phase appears, in addition to continuing the process in the previous stage, the solid phase reaction and diffusion intensify, the plastic flow is enhanced, and the sintered body shrinks significantly.

3. Liquid phase sintering stage

When the liquid phase appears in the sintered body, the shrinkage is completed quickly, followed by a crystallization transformation, forming the basic organization and structure of the alloy.

4. Cooling stage

In this stage, the organization and phase composition of tungsten steel undergo certain changes with different cooling conditions. This feature can be used to heat treat tungsten steel to improve its physical and mechanical properties.

At this point, you should also know why car tires use carbide anti-skid spikes~ Anti-skid spikes are consumables. They shrink as they are worn and worn every day. Although they cannot be replaced every three or five days, they always want to "solve the problem once and for all" and save trouble. Carbide anti-skid spikes, as the name suggests, are hard and wear-resistant, just right. Of course, the most important point is - for driving safety!
