In this paper, we describe the first example of a sustained galvanic coating deposited on a surface from a non-aqueous liquid. We present the surface characterization of electroless silver deposits on copper substrates from a solution of Ag(+) ions in an ionic liquid based on a choline chloride (ChCl) eutectic. Through a study of these deposits and the mechanism of formation using acoustic impe...

The present study outlines the use of Taguchi parameter design to minimize the wear performance of electroless Ni-B coating by optimizing the tribological testing parameters. The tests are carried out in a multitribotester and the three parameters viz. load (L), speed (S) and time (T) are considered with three levels each. An L27 array is used to accommodate the three factors as well as their i...

Sodium-ion batteries (SIBs) are emerging as potential stationary energy storage devices due to the abundance and low cost of sodium. A simple and energy efficient strategy to develop electrodes for SIBs with a high charge/discharge rate is highly desirable. Here we demonstrate that by surface modification of Ge, using electroless deposition in SbCl3/ionic liquids, the stability and performance ...

In this research, tribological characteristics of Ni-P electroless coating and double-layered Ni-P/Ni-B electroless coating were studied. For this purpose, Ni-P electroless coating with 25 μm thickness was initially applied to the surface of steel Ck45 samples; then, a double-layered Ni-P/Ni-B electroless coating, including inner layer of Ni-P with 15 μm thickness and outer layer of Ni-B with 1...

Electroless cobalt films have been obtained by deposition using a plating bath containing two reducing agents: dimethylamineborane (DMAB) and sodium hypophosphite. This formulation allows spontaneous activation on copper followed by auto catalytic electroless plating. CoWBP and CoBP films are proposed as diffusion barriers and encapsulation layers, for copper lines and via contacts for ULSI int...

The improvement of working life is the main purpose this paper to evaluate mechanical properties electroless Ni–P coatings radial micro journal bearings. study was carried out using different plating parameter combinations, namely, pH values solution (6, 7, and 8), deposition time (10, 20, 30 min), bath temperature (60, 80, 95 °C). structure, surface morphology, hardness, wear resistance were m...

Since the die-casting mold repeats rapid heating and cooling during operation, defects such as heat checks generate. Therefore, quality life of are degraded. To improve these demerits, improvement thermal conductivity material is effective. In this study, carbon fibers were added to SKD61(40CrMoV5) tool steel fabricate composites with high conductivity. fiber has a chemical reaction steel, elec...
