Problems solved by technology

At present, the metal wear-resistant materials widely used mainly include alloy steel and cast iron-based wear-resistant materials. The former has good toughness, but has the disadvantages of low hardness and poor wear resistance.
Although alloy steel technology has been greatly developed, there are still many problems, such as wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, cost, etc. It cannot meet the requirements of production, and further improvement is needed. Another part of the automobile manufacturer only strengthens the strength or impact resistance of metal materials alone, which cannot guarantee the maximum protection for the occupants of the car in the event of a collision. Therefore, an improvement is urgently needed. technology to solve the above technical deficiencies
