Abstract: The present disclosure relates to a novel method for producing a field grading powder, to novel field grading powder and their uses and method of uses. The method for producing the field grading powder with semi-conductor properties comprises the steps of i) ball milling under high energy a metal powder and a boron compound for creating an homogenous powder, ii) firing the homogenous powder at a temperature and a time sufficient to create a metal boride powder, and iii) cooling down the metal boride powder from step b) for obtaining a field grading powder having semi-conductor properties.

Abstract: The invention relates to an improved composite material comprising a metal matrix component containing Fe and Al and a ceramic component containing refractory hard metals and metalloids or non-metal elements. The ceramic component consists of ceramic nanoparticles whose dimension are below 100 nm. It also relates to a method of preparing this composite material in the form of a coating, which consists of using a thermal spray technique and a powder which is synthesized by high energy mechano-chemical reactions between the components of the composite. The ceramic component of the composite is formed in situ. The above composite material is particularly useful as protective coatings for tribological applications.
