Abstract: A railroad wheel has a wear resistant flange (3) or tire or rim, comprising the surfaces, which can touch the rail during travelling. On the circumferential outer surface (4) of flange (3) of the wheel (2) an anti-abrasion layer (1) is placed in a durable manner.
Abstract: A method for regenerating and increasing durability of a mill roll, which is characterized in that lateral working surfaces (2) of a mill roll (1), having the width of 20 mm to 400 mm, are covered preferably by means of the laser cladding with a layer of metallic material (3) having the thickness of 0.1 to 4.0 mm, preferably 1.5 to 2.0 mm.
Abstract: The present invention refers to a method of laser cladding of a metallic coat on a metal element. The method consists in hardening the metal surface, favorably by laser, and then laser cladding of at least one layer of metallic material.
Abstract: A method of applying a protective cladding, particularly to gas-tight membranes of energy boilers involves coupling of two gas-tight membranes (2) together, and then soaking a pair of gas-tight membranes (2) coupled together at 300° C. to 800° C., favorably at around 700° C.; afterwards, the membrane (2) surface where a cladding (1) is to be applied is cleaned, a pair of gas-tight membranes (2) coupled together is mounted on a positioner and then preheated up to 80° C. to 600° C., favorably to around 300° C.-450° C., and then the cleaned and preheated surface of a pair of gas-tight membranes (2) coupled together is covered with a protective cladding (1), wherein a protective cladding is applied at a thickness of 0.1 mm to 3.00 mm, favorably around 0.6 mm, and then the entire pair of gas-tight membranes (2) coupled together with a cladding (2) is finally soaked at 300° C. to 800° C., favorably at around 700° C.
