Objects of the invention: diamond-like coating, method for its plating on the product surface and dental bur with this coating. The field of the invention: producing wear-resistant diamond-like coatings on metal and non-metal products, in particular, on medical tools. The essence of the invention: a layer of diamond-like substance plated on the substrate by way of carbon deposition in the gas phase under the conditions of reduced pressure is an aggregate of successive sub-layers of diamond-like coating with reduced concentration of contaminants in the sub-layers interfaces areas, the layer is plated in a sealed chamber under pressures lower than atmosphere pressure controlling the product temperature during the deposition process by the method comprising plating a metal sub-layer from a separate stationary source of metal plasma and further plating diamond-like coating on products being under floating voltage, wherein before turning on each of the metal or carbon plasma sources the plasma flow is completely blocked with a shutter, then the corresponding source is turned on, and in the predetermined period of time the shutter is made open. Such a coating is plated on a dental bur. The technical result: increase of the coating thickness and increase in its strength and wear resistance.
