DLC stands for “diamond-like carbon”. It’s a coating process using diamond-like carbons. This durable and friction-reducing coating essentially comprises diamonds measuring just a few nanometres across, coated in graphite. Thanks to its diamond-like layered structure, DLC has exceptionally hard surface properties, making it substantially harder and more durable than ultra-hardened grades of steel. It’s also more corrosion-resistant and has higher anti-allergenic properties. DLC coatings are harder than standard PVD coatings and offer greater resistance to scratches.
