background: despite wide application of chromium in electroplating industry, the pulmonary effects of chronic exposure to this chemical have not been extensively studied and are subject of debate and controversy. this study was, therefore, undertaken to further address this issue.   methods: the study population consisted of a group of 15 workers with a history of past and present occupational ...

background: chromium (cr) is the most important element used to plate other metals and electroplating factories are still consid­ered to be the most important industries which pollute the environment to this metal. this paper describes a study con­ducted to determine the efficiency of reverse-osmosis (ro) as a membrane technique for removal of cr from wastewater sam­ples synthetically prepared ...

Materials synthesis often provides opportunities for innovation. We demonstrate a general low-temperature (260°C) molten salt electrodeposition approach to directly electroplate the important lithium-ion (Li-ion) battery cathode materials LiCoO2, LiMn2O4, and Al-doped LiCoO2. The crystallinities and electrochemical capacities of the electroplated oxides are comparable to those of the powders sy...

Synergism of Saccharum officinarum (sugarcane) and Ananas comosus (pineapple) extract additives on the quality of electroplated zinc on mild steel in acid chloride solution was investigated experimentally at ambient temperature (*28 C). The experiments were performed at different plating times (15 and 18 min), additive concentrations (2, 2.5, 3 ml/50 ml of acid chloride solution), pH 5, tempera...

The fatigue behavior of Gray Cast Iron is affected to its microstructure, strength, ductility, residual stress and surface roughness etc.... In general, fatigue life increase as the magnitude of surface roughness decrease or the surface hardness increases by surface treatment. As the consequence of conducted high temperature oxidation in subsurface layer of cast iron pores have been creating, c...

The continuous and rapid increase of areal density in magnetic data storage systems required a continuous increase of the coercivity of the storage media. In order to be able to record on these everhigher-coercivity media, new soft magnetic materials for pole tips with increased magnetic moment had to be developed. Significant progress has been made during the last few years in electroplating a...
