Electrospark deposition (ESD) was developed in the Soviet Union and came to the USA when one of the national laboratories, used it for depositing zirconium on stainless steel. This is a good technique to put a metallic or a cermet such as WC, TiB on a component for wear resistance. The...
I searched the Internet for a company or an organization who could design a machine for chromium carbide overlay on small components. I am familiar with large scale systems for steel plates and pipes. I would like to work with a designer-manufacturing company for overlay coating for small...
Above 1400 F heat transfer by radiation is greater than by convection, During radiative heat transfer, energy is transmitted from a refractory wall at higher temperature than the metal part to be heated. Generally the emissivity of the refractory is less than 0.8. NASA has developed high...
Grips used in tensile testing can be refurbished and used again. Are there any tensile testers who discard grips and wedges when they gall and the specimen begin to slip?
Fretting is a wear phenomena when two steel parts for example a holder and spindle mouth, rub against one another. Fretting is caused by imperfect mating between
toolholder taper and spindle, creating vibration and heat which develops the fretting. A cermet coating of tungsten carbide can reduce...
thread284-275265 I saw this post to-day after I joined eng-tips. I had worked in a stainless steel hot strip plant. One of the difficulty faced by us was the wear of the rotary shear knives for edge trimming/cutting. Their edges got dull after one shift and we had to change the rotary shear...
I am doing research on how micro deposit of hard materials like tungsten carbide can reduce wear of components. I am interested in knowing which mechanical components wear out in less than a day or week. The wer should be restricted in a small ares
