ABSTRACT:
A paper pulp defibering or refining plate in accordance with the invention comprises a comminuting surface having a large number of ridges separated by grooves. The plate body is made from a first material such as stainless steel or cast iron providing the overall mechanical strength of the plate in use. The upper part of the ridges is a layer of an abrasion resistant material based on grains of tungsten carbide bound in a metal alloy whose melting and brazing characteristics are appropriate to laser resurfacing on the plate body. The ridges are resurfaced successively by scanning a laser beam and a powder spray nozzle in one or more passes.
