——What makes your woodworking knives so gorgeous and beautiful?
——The secret is coating.
——What kind of coating is that?
——The coating is named DLC, an abbreviation for ‘Diamond-Like Carbon’.
——In addition to the good-looking appearance, does DLC coating bring any other benefits to woodworking blades?
——Of course there are, higher hardness, more wear-resistant, lower friction coefficient, longer life, etc., and let me tell you one by one.
Well, Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from some of those properties.
Due to DLC coating is tailored to have a combination of high hardness and high elastic modulus, low coefficient of friction, lubricity, abrasion, and corrosion resistance, good chemical resistance.
it has become an ideal coating material for high-speed steel and cemented carbide tools. It can also be widely used in machinery, molds, Knives, automobiles, electronics, optics, biomedicine, aerospace, decorative appearance protection, such as watch casings, jewelry accessories, mobile phone casings and other fields. Today I will take you to understand the role of DLC diamond-like carbon coating performance on woodworking reversible inserts.
Compared with the traditional uncoated woodworking reversible knives, our coated woodworking tools adopt DLC coating, which has a better performance and longer life. The thickness of the coating is 0.2~0.5um, which not only has a high hardness (5000~10000HV), increases the overall wear resistance of woodworking blades by 40%; it also reduces the friction coefficient of the cutting edge (the friction coefficient is 0.05~0.1), which makes cutting more smooth, these performances have greatly improved the service life.
