CIM Proprietary Technologies

TungTough™ and TungHard™ are specially formulated tungsten carbide overlay (WCO) applied by plasma transfer arc welding (PTAW). They are designed to withstand high impact and high abrasion conditions.

 

TungCast™ and TitanCast™ are exclusively CIM products known for their exceptional durability, toughness and wear resistance. The tungsten carbide or titanium carbide are metallurgically bonded in chrome white iron, the combination of the toughness of the base metal and hardness of carbides enable the product to excellent in high-impact applications.

 

DuraPlate™ is a chrome carbide overlay (CCO) manufactured by special sub arc welding (SAW).  The CCO overlay can get up to 25 mm thick with a single pass and the overlay surface is smooth and free of welding beads and cracks.

CIMSiC™ is a silicon carbide ceramic with excellent corrosion resistance, erosion resistance and thermal shock resistance. CIM has three types of ceramic products, Nitride Bonded SiC (NBSC), Reaction Bonded SiC (RBSC), and resin bonded SiC for your applications. 

CIMTiC™ is sintered titanium carbide (TiC) with excellent wettability with the steel. It is designed to combine sintered TiC with iron or steel through the cast-in process. The sintered TiC is metallurgically bonded in the base metal during the casting process and eliminates the residual stress that usually happened in the brazing process.

CHROME WHITE IRON (CWI)

At CIM, we collaborate with industry partners to find solutions for common wear problems; because of this, CIM has developed TungCast™ and TitanCast™ with Tungsten Carbide (WC) or Titanium Carbide (TiC) metallurgically bonded in high chrome white iron (ASTM A532 IIB or IIIA), mild steel, or high manganese steel.

The WC or TiC reinforced layer is 15 - 25 mm. These products are extensively used in aggressive wear and high-impact services.

TUNGSTEN CARBIDE OVERLAY (WCO)

Plasma Transferred Arc (PTA) weld is a high-energy, low heat welding process that provides minimal interaction with the base material while allowing the application of a thick weld overlay. Commonly applied overlay includes tungsten carbide, chrome carbide, and titanium carbide.

CIM has developed proprietary PTA TungTough™ and TungHard™ WCO. The ideal combinations of high hardness, superior wear resistance and toughness make them the preferred materials for extreme wear applications.

SILICON CARBIDE CERAMIC (SiC)

CIMSiC™ is a silicon carbide ceramic with excellent corrosion, erosion and thermal shock resistance. CIM has developed three types of ceramic products, Nitride Bonded SiC (NBSC), Reaction Bonded SiC(RBSC), and resin bonded SiC.

CIMSiC™ is extensively used on slurry pump suction liner, impeller, volute and hydrocyclones in mining, coal-fired power generation and smelting industry.

Chrome Carbide Overlay (CCO)

CIM DuraPlate™ is a composite Chrome Carbide Overlay (CCO) manufactured by special automatic welding technology.  The overlay surface is smooth and free of welding beads and check cracks.

The CCO overlay can be made up to 19 mm thick with a single pass and a maximum of 25 mm. The hardness, G65 and chemistry are consistent through-thickness of the overlay.

The microstructure of the cryptocrystalline martensitic matrix with precipitated chrome carbide and the other composite carbides makes the DuraPlate™ harder and more abrasion-resistant than typical CCO materials.

CIMTiC™

CIMTiC™ is sintered titanium carbide (TiC) with excellent wettability with the steel. It is designed to combine sintered TiC with iron or steel by the cast-in process. The sintered TiC is metallurgically bonded in the base metal during the casting process and eliminates the residual stress that usually happened in the brazing process. CIMTiC™ is extensively used to build rollers for steel rolling, drilling bits, crusher teeth, shovel teeth, and hammer crusher tips.

COATING

Composite polymer ceramic coating

CIM developed a polymer-based ceramic coating for corrosive and erosive services. Hard ceramic particles SiC, AI2O3, SiO2, or Si3N4 were combined with the polymer, and the bonding strength could get above 15 MPa.

corundum ceramic coating

Corundum ceramic coating is made from 2600 ̊C molten alumina (AI2O3) centrifugally formed inside the steel pipe wall. The hardness of corundum ceramic coating is above 90 HRC, and it has excellent wear resistance, corrosion resistance and thermal shock resistance.
