Material deterioration due to erosion and oxidation in high-temperature environments is a major cause of wear power plants, aircraft engines petrochemical industries. NiCrSiB based surface coatings using thermal spray techniques such as High-Velocity Oxy-Fuel (HVOF) offer cost-effective route improve the tribological properties for range substrate materials. The study investigates resistance HV...

Carbide composites are materials based on the carbide phases of the refractory or high melting temperature metals. The hard carbide phase (WC, TiC) is usually embedded into soft matrix – pure metals (Fe, Co, Mo, Ni and others) or their combinations. The hard phase supports high hardness and strength of the carbide composites, while matrix is needed for toughness and plastic properties. The ordi...

Considered as a plague for numerous industrial assemblies, fretting, associated to slight oscillatory displacement, is encountered in all quasi-static contacts subjected to vibration. Depending on sliding conditions, cracking or wear damage can be observed. During the past three decades there has been a huge development in surface treatments. Thousands of new surface treatments and coatings are...

Cooperative Extension has a long history of using radio broadcasts in educational programming. The Minneapolis, MN-based CBS affiliate WCCO Radio 830AM contacted the University Minnesota (UMNExt) 2013 to reinstate an 8:00 AM Saturday live gardening show titled “Smart Garden”. After several years doing show, we wanted determine effectiveness getting information listeners, what people were differ...
