This article aims to present results on research, recently developed, and related wear of equipment meet the challenges mining industry. Emphasis is done iron ore in Brazil due relevance sector for its economy tribology assets productivity. Results considerations cover (conveyor belts, pipelines) development high chromium cast (HCCI) microstructures face wear. Under wet erosive caused by pumped...

The aim of this work was to obtain a wear-resistant coating by surfacing with powder electrodes the multi-component system Fe-Ti-Mo-B-C using currents that are lower than standard values. theoretical calculation thermal cycle during process performed determine impact on working surface outside melting zone. An experimental determination temperature effect for comparison calculated one. Structur...
