The invention relates to a plastic product, comprising plastic substrate. The plastic product is characterized in that the product also comprises a copper coating, a nickel coating, a chrome coating and a ceramic coating from the surface of the plastic substrate to the outside in sequence; the ceramic coating is one or more layer of titanium nitride, titanium carbide and titanium carbonitride. The plastic product made by the invention has excellent wearing resistance, the film formed on the surface of the plastic product has excellent adhesiveness, and the plastic product that is obtained finally also has ceramic texture and good handfeel.

The invention relates to a drawing die and particularly relates to an Al2O3-TiC / Al2O3-TiC-CaF2 self-lubricating laminated ceramic drawing die and also relates to a preparation method of the laminated ceramic drawing die. The technical scheme is as follows: the Al2O3-TiC / Al2O3-TiC-CaF2 self-lubricating laminated ceramic drawing die mainly comprises an Al2O3-TiC layer ceramic material and an Al2O3-TiC-CaF2 layer ceramic material, wherein the Al2O3-TiC layer ceramic material comprises the following components according to the volume ratio: 45% of aluminum oxide, 50% of titanium carbide, 0.5% of molybdenum, 4.5% of nickel and trace magnesium oxide and yttrium oxide; the Al2O3-TiC-CaF2 layer ceramic material comprises the following components according to the volume ratio: 30% of aluminum oxide, 60% of titanium carbide and 10% of calcium fluoride. The Al2O3-TiC layer ceramic material and the Al2O3-TiC-CaF2 layer ceramic material are laminated according to the design requirements of different wire processing sizes for the ceramic drawing die, and the ceramic die obtained after sintering retains higher hardness and strength, meanwhile, the toughness of the die is improved, and in addition, the whole die has a self-lubricating characteristic in the drawing process, so that the wear reducing and resisting effects are remarkable.
