Abstract In this paper, the pressing and sintering properties of three kinds copper-coated chromium composite powder copper-chromium mechanical mixed with same copper content were compared studied. The was prepared by a diffusion method, liquid electroless plating method an added binder. results show that increase in content, advantage copper-clad is more obvious. density, hardness, size shrink...

In order to form model aluminide coatings for studying critical issues related to their high temperature oxidation and corrosion performance, a laboratory chemical vapor deposition (CVD) procedure is being used to more rigorously control the coating process in terms of composition, purity and microstructure. One ferritic (Fe-9Cr1Mo) and one austenitic alloy (304L) were selected as substrate mat...

Magnesium-based bulk metallic glass matrix composites (BMGMCs) have better plasticity than the corresponding bulk metallic glasses (BMGs); however, their strength and density are often compromised due to the fact that the effective reinforcement phase is mostly plastic heavy metal. For lightweight SiC-particle reinforced BMGMCs, interface wettability and the sharpness of the particles often red...

In this paper, we present recent results obtained for pulse plating of 1.8 T CoNiFe alloy. As a starting point, a comprehensive model is developed that explains and mathematically describes the phenomenon of pole tip depression observed in the case of direct current deposition. Based on this model and its results the parameters like pulse time, rest time, and magnitude of the pulse current jpp ...

richlorotrifluoroethane (CFC-113) T has been widely used to remove machining oils from metals after those metals have been stamped and formed. In many cases, removal of the hydrocarbon machining oils is necessary before the metals can undergo further processing such as electroplating. In other situations, the stamping occurs as the last step in the process and the formed metal parts must be cle...

In this study, we systematically examined the influence mechanisms of introduced cobalt coated alumina (Co-coated Al2O3) particles on microstructure and properties cobalt-chromium-molybdenum (CoCrMo) alloy printed by Laser Powder Bed Fusion (LPBF). The Co-coated Al2O3 composite powders with different density coating were prepared varying load from 1 g/150 mL to 2 during electroless plating proc...

Background: Distal tibia fractures are among the most common bony injuries, with a significant rate of nonunion anddelayed union. There are multiple methods for the management of distal tibia fractures. Among the plating methods,there are bridge plating and compression plating techniques. There is still a lack of evidence about whether one methodhas a higher rate of union than...

This paper focused on a novel method of electroless plating ruthenium (Ru) on solid or porous substrates like porous stainless steel (PSS) discs or ceramic tubes. A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the success...
