NOVELTY - The workpiece comprises a base body (1) and a covering layer (6). The covering layer comprises three-fold layers including a layer of silicon (Si)-diamond-like carbon (DLC), a layer of DLC, a layer of Me-DLC and 5-10 atm.% of hydrogen, where Me comprises tungsten (W), and has a hardness of 15 to 50 GPa and a part volume of 40x 40x 40 to 200 x 200x 200 nm3. Each partial volume has each 8-20 atm.% of Si and 10-20 atm.% of Me. The covering layer has a thickness of 0.8-2.0 mu m, an ultrasonic indentation hardness of 25-40 GPa, and a coefficient of friction of 0.05-0.1.    USE - The workpiece is useful as a component of an internal combustion engine, a transmission part of an automotive gear, a connecting rod, a transmission component, a gear, a shaft, a bushing, a bearing, a ball bearing, a needle bearing, a piston ring, a piston pin, a cylinder volume socket component of a fuel injection device for direct injection of diesel or gasoline for automobiles, a component of a valve train of an automotive engine, a bucket tappet, a cam, a rocker arm, a tappet, a linear guide, a catch bracket for automobile doors, a bushing or a solar cell.    ADVANTAGE - The workpiece exhibits increased resistance to wear and friction and long service life, and provides low friction losses to the engine.    DETAILED DESCRIPTION - The workpiece comprises a base body (1) and a covering layer (6). The covering layer comprises three-fold layers including a layer of silicon (Si)-diamond-like carbon (DLC), a layer of DLC, a layer of Me-DLC and 5-10 atm.% of hydrogen, where Me comprises tungsten (W), ME is tungsten, and has a hardness of 15 to 50 GPa and a part volume of 40x 40x 40 to 200 x 200x 200 nm3. Each partial volume has each 8-20 atm.% of Si and 10-20 atm.% of Me. The covering layer has a thickness of 0.8-2.0 mu m, a ultrasonic indentation hardness of 25-40 GPa, and a coefficient of friction of 0.05-0.1, a wear coefficient of 0.5-1.5x 10-15 m3/(N.m) according to Kalotest with a suspension of Al2O3 powder in glycerol and a bonding strength of HF1 to HF2 measured by Rockwell A test for base body made from hard metal and Rockwell C adhesion test, and further comprises 0.01-6 atm.% of an additive. The three-fold layers are arranged in a periodical manner, and have a thickness of 15 nm. The silicon content in the covering layer increases while increasing distance of the base body. The workpiece further comprises an adhesive layer disposed between the covering layer and the base body, a first intermediate layer arranged between the cover layer and the base body or the adhesive layer, a second intermediate layer disposed between the first intermediate layer and the covering layer, and a third intermediate layer disposed between the covering layer and the base body. An INDEPENDENT CLAIM is included for a method for physical vapor deposition coating of workpieces.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a workpiece.
