Bimetallic screw Products features :Plasma Alloy Coating Spraying The PTA powder plasma welding applies the positive and negative electrodes of arc welding, allowing the welding path to be completely welded with the base material. The minimum possibility of the welding path becoming less rigid fully prevents the welding layer from peeling off thereby effectively upgrading the life time of the screws. PTA is a Nickel-based alloy. Its chemical composition includes Ni,WC,CO,Fe,Si,B,Cr and C. Outstanding Features of Bimetallic Screw 1.Hardness HRC 56 / 62 2. Hardness layer reaches 1.5 m/m thickness.hardness does not decrease with depth. 3. Hardness does not decrease under normal temperature. 4. Outstanding corrosion-resistance. 5. Abrsion resistance / wear resistance on the hardened layer is 2~3 times higher than that treated by conventional heat treatment. Bimetallic barrel/cylinder Products features: Centrifugal Casting (Inlay Alloy) Bimetallic barrel is casting a layer 2-3 mm of wear-resisting corrosion resistant, high temperature resistant alloy in Barrel wal l,the effective use of life greatly improved than ordinary nitrogen, for processing engineering plastic, fluorine plastic, get together the PSF, ppo special type of plastic etc, the superiority of the bimetallic is especially remarkable. According to
different function, we adopt different alloy and welding and way. Surface Treatments: Thickness of Hard Chrome Plating Layer: 0.05-0.10mm Hardness of Hard Chrome Plating Layer: 950HV Depth of Bimetallic Layer: >2mm Hardness of Bimetallic Layer: HRC55-72 Backing material(38crmoala) Chemical composition (weight%)and Main Feature Backingmaterial Hardness Chemical composition (weight%) C Cr Si S Mo P Mn Al 38CrMoALA Hv1000-1200 0.35~0.42 1.35~1.65 0.20~0.40 0~0.030 0.15~0.25 0~0.035 0.300~0.60 0.70~1.10 Mainly used to make precise size, high wear resistance, high fatigue strength of the azotized parts, such as the cylinder cover, seating, precision grinding spindle etc.
