Metallurgical Soldering of Duplex CrN Coating in Contact with Aluminum Alloy

Soldering of Aluminum Matrix Composites Sicp/a356 and Kovar Alloy

Article history: Received 28.3.2013 Received in revised form 26.4.2013 Accepted 29.4.2013 Aluminum matrix composites containing 55% SiC particle reinforcing phase/SiC reinforcement phase particle and Kovar alloy 4J29 were chosen as the base metals. After nickel plating on the surface of SiCp/Al, two kinds of materials were soldered together by using Zn-Cd-Ag-Cu as the filler metal and ZnCl2 as ...

Metallurgical and mechanical properties of laser cladded AlFeCuCrCoNi-WC10 high entropy alloy coating

In spite of excellent corrosion resistance, good ductility and low cost of AISI 316 austenitic stainless steel, the low hardness and poor mechanical charecteristic of material restricts its applicability in several industrial services. To improve upon mechanical properties AlFeCuCrCoNi-WC10 high-entropy alloy coatings were deposited via laser cladding on austentic stainless steel AISI 316 subst...

Investigation of Coating Cracking and Fatigue Strength of 7050-T74 Aluminum Alloy with Different Anodize Coating Thicknesses

Direct Electrosynthesis of Polyaniline–Fe2O3 Nanocomposite Coating on Aluminum Alloy 5052 and Its Corrosion Protection Performance

The synthesis of polyaniline- Fe2O3 nanocomposite coating on aluminum Alloy 5052 (AA5052) surface has been investigated by using the galvanostatic method. The anticorrosion performance of polyaniline-Fe2O3 coating was investigated in 3.5% NaCl solution by the open- circuit potential (OCP), Tafel polarization technique and Electrochemical Impedance Spectroscopy (EIS). The corrosion rate of polya...

Biocompatibility of a titanium–aluminum nitride film coating on a dental alloy

The purpose of this investigation was to develop a coating technique and to study the characteristics of titanium–aluminum nitride [(Ti,Al)N] films deposited on a base-metal alloy (Wiron88R) substrate. Titanium–aluminum nitride thin films were deposited on the alloy surface using a reactive radiofrequency sputtering method. The electrochemical properties of three specimens with and without coat...
