چکیده
In order to meet the design requirements of lightweight artillery and adopt method double-glow plasma nitriding solve problem low hardness poor abrasion resistance Ti alloy, BTi-62421S high-performance titanium (Ti) alloy was selected as experimental material replace gun steel. To study effect different nitrogen (N) concentrations on heat scouring performance investigate influence alloying elements under same parameters compared with commonly used TC4 argon protective gas by continuously increasing N concentration (Ar/N2 = 1:1, 1:2, 1:3). It found that honeycomb structure surface sample thickness coating increased continuously, reaching a 15 μm, while depth nitride particles extending from substrate also increased, maximum 26 μm. The orientation TiN changed 37° 62°. showed negative correlation coefficient frictional abrasion, which significantly improved heat-resistant alloy.

متن کاملSurface alloying of Mg alloys after surface nanocrystallization.
Surface nanocrystallization using a surface mechanical attrition treatment effectively activates the surface of magnesium alloys due to the increase in grain boundary diffusion channels. As a result, the temperature of subsequent surface alloying treatment of pure Mg and AZ91 alloy can be reduced from 430 degrees C to 380 degrees C. Thus, it is possible to combine the surface alloying process w...

In recent year’s aluminum and aluminum alloys are widely used in automotive industries. These are light weight (density of about 2.7g/cc),having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity. High machinability and workability of aluminum alloys are prone to porosity due to gases dissolved during melting processes. However, in the engi...
