METHOD FOR COATING A SURFACE WITH A SPRAY MATERIAL AND FUNCTIONAL LAYER ACHIEVABLE WITH THIS METHOD |
| 摘要 |
A method for coating a substrate, in which a wire-shaped spray material is melted in an electric arc and is deposited as a functional layer on the substrate. The invention also relates to a functional layer which can be produced on the substrate by this method. The functional layer has a high hardness value and good corrosion resistance on exposure to diesel fuel with a high sulphur proportion. |

1. A functional layer reduced in terms of frictional power, comprising an iron-based alloy having:
a predominantly martensitic structure, and the following alloy components specified with the indicators of nickel equivalent (NiÄ) and chrome equivalent (CrÄ) of the Schäffler diagram:
CrÄ>10 andNiÄ>CrÄ−9 andNiÄ<19−0.8*CrÄ each with regard to a total weight. |
