abstract |
The present invention relates to a tool with an edge, such as a doctor blade, for use as a wipe in various stages of the manufacturing process in the manufacture of pulp and / or paper. This tool consists of a steel strip with edges. The edge portion of the belt-like member is provided with a wear-resistant coating formed by laser technology. Here, a metal bond exists between the coating and the steel strip member, and therefore, a surface hardness of a level exceeding 850 HV can be realized. Thereby, a doctor blade having wear resistance with a long service life can be realized. |
