Abstract
A cast structural element of a pump, filter or compressor is disclosed with wear resistant layer comprising in situ produced composite material based on alloys, especially cast iron based alloys, reinforced with tungsten carbide in the form of crystals and/or particles, characterized by the microstructure of the composite material within the layer comprising faceted crystals and/or faceted particles tungsten carbide that provide uniform macroscopic and microscopic distribution, wherein the crystals and/or particles of tungsten carbide include irregular and/or round and/or oval nano and/or micro-areas filled with alloy based on metal. A method of producing the cast structural element in the form of a pump, filter or compressor is also disclosed.
