Abstract NiAl intermetallic coating thickness of about 50 μm was fabricated on hypo-eutectoid steel by mechanical alloying using pre-activated Ni–Al composite granules as material. First, Ni and Al powders were mixed with the composition Ni-50 at.% mechanically activated in a planetary ball mill, until this powder mixture, having maximum activity (9 cm sec −1 ), formed after 120 min milling at 200 rpm. The then taken out from mill just before critical time, i. e. time which these synthesize...
In this work, we proposed a novel mechanical alloying method to deposit Nix-Tixintermetallic coating on various metallic substrates using laser treatment. Three different (Al-based alloy, Ti-based and hypoeutectoid steel) were used, 50–70 μm thick NixTix was deposited during the process. For alloying, used self-constructed vibratory ball mill (single chamber) for treatment, “TrumpfTruDisk 1000” machine equipped with four-dimensional control system “Servokon” designed specifically...
In this work, Al-matrix composite reinforced with 20% NiAl intermetallide was fabricated, in situ, by high-energy ball milling. The main aim and novelty of research are to utilize the heat produced during synthesis Ni–Al powder while preparing composite. trapped chamber a mill can be used for various purposes, i.e., it enhance bonding between reinforcing particles matrix significantly. Also, post-mechanical alloying process (annealing, etc.) eliminated. Highly activated granules were as...
A hermetic reciprocating compressor is one of the most critical parts for energy efficiency a household refrigerator. Piston-cylinder contact in accounts loss. The tribological performance piston-cylinder pair can be enhanced by introducing micro-texturing on piston surface. In this research, an experimental study presented to tribologically assess effect micro-textured hermetically sealed compressor. micro-texture surface was prepared laser texturing method. Four different micro-textures...
