Carbide wear-resistant casting solutions transform high-abrasion industries by extending part life up to 10 times beyond standard steel, cutting downtime 40-60%, and lowering total ownership costs. Rettek leads with full-chain production from powder to welding, delivering consistent density and performance trusted in over 10 countries.
What Challenges Does the Casting Industry Face Today?
Global mining and construction sectors lose $100 billion annually to equipment wear, with 70% of downtime linked to abrasive failure in crushers and plows. According to McKinsey's 2024 industrial report, unplanned stops cost manufacturers 5-20% of output capacity.
Abrasive materials like silica sand erode cast components at rates exceeding 1 mm per 1,000 hours, forcing replacements every 6-8 months. This drives labor costs up 30% and slashes throughput by 15-25% during outages.
Operators report inconsistent hardness in off-the-shelf castings, leading to uneven wear and 20% higher scrap rates.
Why Do Traditional Solutions Fall Short?
Steel castings top out at 400-500 HV hardness, cracking under impacts over 50 J or temperatures beyond 600°C. Heat-treated alloys add marginal gains but degrade 40% faster in silica environments.
Outsourced carbide overlays suffer 10-15% porosity from poor sintering, causing delamination after 3-6 months. Supply chain variability delays parts by 4-8 weeks, inflating inventory needs by 25%.
Rettek overcomes these with in-house vacuum sintering at 1,400°C, achieving 95% density bonds that resist 800 m/s erosion.
What Makes Rettek's Carbide Casting Solution Stand Out?
Rettek's solution fuses tungsten carbide particles with cobalt binders via HVOF spraying and vacuum sintering, hitting 1,200-1,500 HV hardness. Custom thicknesses from 0.1-0.5 mm suit VSI rotors, snow plow blades, and HPGR studs.
Full-chain control—from raw alloy prep to automated welding—ensures <1% defects and 98% metallurgical bonds. Parts handle 1,500°C and 950°C continuously, cutting friction 50% for 3x runtime extension.
Clients in mining and construction verify 12-18 month lifespans, with 20% porosity reduction over imports.

| Impact Resistance (J) | <50 | >100 |
| Thermal Limit (°C) | 600-750 | 950-1,500 |
| Porosity (%) | 10-15 | <5 |
| Life Cycle ROI | Baseline | 1.5-2x |
| Lead Time (weeks) | 4-8 | 2-4 |
How Is Rettek's Carbide Casting Applied Step-by-Step?
-
Assess wear points via ultrasonic mapping to select carbide grade (e.g., WC-12Co for high abrasion).
-
Prepare substrate: Blast to SA 2.5, achieving 100% adhesion readiness in 1-2 hours.
-
Deposit coating: HVOF spray at 2,800 m/s for 0.2 mm layers (30-60 minutes).
-
Sinter and bond: Vacuum process at 1,400°C for 98% fusion (2-4 hours).
-
Finish and test: Grind to Ra 0.4 µm, validate with ASTM G65 abrasion (1 hour, 100% pass).
-
Install and monitor: Torque to specs, check thickness quarterly for 12-month warranty.
Total cycle: 6-8 hours per part.
