water solutions Molib-techTM Nowadays, a new concept of quality is driving firms to expand their offerings of products and services in order to meet specific needs and build solid partnerships with their customers. Through a complex research project, Zenit has developed Molib-TechTM a new material to: • increase components' strength • improve reliability • keep performance constant over time even in extreme duty conditions. Molib-techTM is an alternative to the conventional ceramic coating process and involves the application of an additional thick layer of a very hard material on the cast iron, to improve products' mechanical and performance characteristics. The technique is defined as "cold" coating, with no high temperatures to cause deformation or stresses in the piece. The metallic molybdenum carbide coating used by Zenit is particularly suitable for preventing serious wear due to erosion or cavitation on pump impellers, suction flanges and bodies.

water solutions The coating forms a mechanical bond to the substrate thanks to the high particle impact speed and the fact that the substrate surface is well prepared through sand-blasting. Unlike the conventional ceramic coating, the uniform layer of metal coating does not cause any change in clearance or loss of performance. The molybdenum carbide coating gives the treated component a surface hardness considerably higher than cast iron (1000/1100 HV), making it suitable for heavy-duty applications and use with abrasive liquids.
