Dense Insulating Coatings in Chromium Oxide
We spray high-purity Cr2O3 powder by plasma spraying to build dense, uniform insulating ceramic coatings on stainless steel, carbon steel, aluminium and titanium substrates. The coating raises high-temperature, wear and electrical insulation performance while extending service life and cutting maintenance cost.
Key Properties
- High electrical insulation - prevents short circuits and leakage in high-voltage equipment
- Stable above 1000 C with resistance to thermal shock and thermal fatigue
- Hardness about 1200-1400 HV for outstanding abrasion resistance
- Excellent chemical stability against acids, alkalis and salts
- Strong bond strength to the substrate with low spalling risk
Typical Applications
- Power equipment: high-voltage switchgear, breakers, transformers
- Electronic components: insulators, capacitors, sensors
- Industrial furnaces: linings and heating elements
- Aerospace: engine parts and thermal protection
- Petrochemical: reactors, piping, valves
Full Service Scope
Equipment assessment, surface preparation, plasma spraying, non-destructive quality inspection and follow-up maintenance support - delivered by an experienced team under strict quality control.
