The nanoindentation test has been applied to evaluate the mechanical properties such as hardness, elastic moduli and deformation behaviors of Fe4N iron nitride layers produced on Armco iron and En40B steel by plasma nitriding, and PVD-TiN coatings deposited on En40B with or without prior plasma ...
Optimization of a single strip tester to measure magnetic properties of electrical sheet steel at medium frequencies Standards such as IEC 60404-10 state a constant length of 940 mm which in reality depends on multiple factors, including frequency and peak flux density... M Owzareck,L Kai,N ...
摘要: PURPOSE: To eliminate the defect of low viscosity of an AlO-TiO thermal spraying material and to obtain a thermal spraying material for allowing the Al2O-TiO thermal spraying material to exhibit its satisfactory corrosion resistance, hot strength and spalling resistance....

It is shown that RE addition in the form of a small solid piece in the centre of the negatively biased work table results in increased nitrogen concentrations in the near surface regions of steel specimens coupled with improved surface hardness properties. The same small piece of RE can be ...
just to solve the power problem of mass communications, and because elongation nylon times higher than the steel, we have high impact and force deformation and recovery capabilities, thus with steel pins compound has good adaptability, furthermore, nylon self-lubricating properties, can greatly reduce...
