Onyx Series
Onyx Series is a superior PVD coating, very durable and long wearing. PVD (Physical Vapor Deposition) is superior to Black Oxide because it bonds hard to stainless steel for a long lasting, strong wear/ corrosion resistance. No toxic chemicals, solvents, or heavy metals are used in this process. Produces virtually zerp harmful byproducts or hazardous waste "green" technology.
Quick Summary
- PVD coatings are very hard which is ideal for wear, scratching, and long life.
- PVD is the most environmentally friendly process.
- Black Oxide MUST be sealed. Without a sealer, corrosion resistance is minimal and the coating washes off.
- Many vendors use alternate names (e.g."anodic black finish" on stainless). Always ask for the actual process and wear/wash off expectations.
- Beware; ask what the warranty is before the black coating washed off and fades.
