Abstract:
1. A mold wall of a continuous casting mold for steel and having plates of copper or a copper alloy and which are either provided with coolant channels or are in a thermally conductive contact with a water tank, the mold wall comprising: a surface that comes in a direct contact with steel; and a protective layer applied to the contact surface and having a thickness of from 10μ to 10,000μ, wherein the protective layer is formed of a binary nickel-cobalt alloy NiCo30 having a hardness of about 400 HV1 and includes dispersing additives with a particle of 1μ to 5μ or nanosize particles with a size of 10–1000 nanometers, wherein the dispersing additives are selected from a group containing: wherein the dispersion layer has adjustable mechanical and physical properties such as wear resistance, and/or temperature resistance and/or tribology defined by a microstructure changeable by varying inclusion of nanosize particles of NiCo 30.
