Cast structural element of a pump, filter or compressor with wear resistant layer comprising composite material based on alloys reinforced with tungsten carbide and the method of producing thereof

A cast structural element of at least one of a pump, filter or compressor together with a wear resistant in situ produced layer comprising:

• composite material based on alloys reinforced with tungsten carbide in the form of at least one of crystals and particles,
• a microstructure of the composite material within the layer comprises at least one of faceted crystals and faceted particles of tungsten carbide that provide uniform macroscopic and microscopic distribution,
• wherein the at least one of faceted crystals and faceted particles of tungsten carbide include at least one selected from the group consisting of irregular, oval, round nano and micro-areas filled with an alloy based on metal;
• wherein a mixture of powders to produce the composite material within the layer consists only of between 93-95% wt. tungsten powder and 5-7% wt. carbon powder wherein another layer comprising the composite material comprises additional types of carbides or borides selected from the group consisting of TiC, MoC, NbC, ZrC, VC, TaC, TaB, TiB2 and mixes thereof.
