Silicon Nitride Ceramic:
Today's high-strength steel and ultra-high-strength Ceramic Substrate Hybrid Integrated Circuit Sheet steel have achieved the lightweight of vehicles and improved the collision strength and safety performance of vehicles. Therefore, they have become an important development direction of automotive steel. However, as the strength of the sheet metal increases, the traditional cold stamping process is prone to cracking during the forming process, which cannot meet the processing requirements of high-strength steel plates. Under the condition that the forming conditions cannot be met, the hot Ceramic Substrate Hybrid Integrated Circuit Sheet stamping forming technology of ultra-high-strength steel plates is gradually being studied internationally. This technology is a new process that integrates forming, heat transfer and structural phase transformation. It mainly uses the characteristics of increased plasticity of sheet metal and decreased yield strength under high-temperature austenite state, and the process of forming through molds. However, thermoforming requires in-depth research on process conditions, metal phase transition, and CAE analysis technology. At present, this technology is monopolized by foreign manufacturers and the domestic development is slow. In the past, in the production of deep-drawn or re-punched workpieces, everyone believed Ceramic Substrate Hybrid Integrated Circuit Sheet that pressure-resistant (EP) lubricants were the best choice for mold protection. Sulfur and chlorine EP additives have been mixed into pure oil to increase the life of the mold has a long history. However, with the emergence of a new metal—high-strength steel and strict environmental protection requirements, the value of EP oil-based lubricants has decreased, and even lost the market.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
