Core Product Features
1. Superior abrasion resistance with special aggregate formula
Filled with titanium alloy and hard carbide particles, its wear resistance is 2–3 times higher than medium carbon steel. Perfect for particle erosion and abrasive wear conditions, effectively extending service life of vulnerable parts and lowering spare parts cost.
2. High-strength cold repair without base metal damage
High bonding strength replaces hot welding completely, avoiding thermal deformation, stress cracking and annealing of shafts and bearing housings. Thixotropic paste prevents sagging on vertical, overhead and inner-hole surfaces for on-site maintenance without full equipment disassembly.
3. Available for precision secondary machining after curing
Dense non-shrink cured layer supports turning, boring, drilling and grinding, accurately restoring tolerance for scratched journals, worn bearing bores and damaged splines/keyways.
4. Excellent impact resistance & dynamic load stability
Outstanding toughness, compressive and bending strength enable long-term operation under rotating friction, alternating load and vibration. Resists peeling and spalling, as well as erosion from engine oil, hydraulic oil, moisture and weak acid/alkali.
5. Wide substrate compatibility & easy operation
Strong adhesion on carbon steel, cast iron, stainless steel, aluminum alloy, copper alloy and most metals. Only simple sanding and degreasing required for surface treatment, greatly reducing equipment downtime.
Application Scenarios
1. Transmission shaft repair: Restoration of worn/scratched shaft journals, damaged splines and keyways;
2. Bearing position reconditioning: Cold repair for worn bearing housing bores, sleeve fitting surfaces and out-of-round holes;
3. Pump & impeller protection: Repair and anti-abrasion coating for eroded pump casings, fan impellers under particle scouring;
4. Heavy machinery maintenance: Wear repair for flow passage components of mining, mixing and conveying equipment, anti-abrasion reinforcement for flanges and sliding blocks.
