ron phosphate coatings have found a wide range of use in the metalI finishing industry as a convenient method for achieving reasonably high levels of corrosion resistance. Flexibility of processing parameters and ease of use are probably the biggest reasons that iron phosphating enjoys its continued popularity. The corrosion resistance of iron phosphate coatings can be dramatically improved by ...

Tremendous potential exists for the growth of metal finishing industry in this century through the development of processes that are either environmentally friendly or are applicable at the nano scale. In the CEE the theoretical and experimental studies are performed to achieve such coatings. Nanostructured alloys and innovative composite materials were developed through adaptation of existing ...

∗ Previous address: Department of Automation, Tianjin University, P. R. China Abstract In steel rolling industry, control of hot metal rolling process plays an important role in assuring high product quality and safe process operation. Although many advanced looper control technologies for finishing rolling process have emerged, looperless interstand tension control of roughing rolling mills re...

in magnetic abrasive finishing (maf), abrasive grains as a tool move on surface and can removechip from surface of work piece. in this study al 6061 tube was considered as the work piece andthe effect of finishing parameters such as gap distance between tube and poles, rotational speed oftube, abrasive ration and finishing time on surface roughness was investigated. the mixture offerromagnetic ...

Low surface quality of as-deposited laser metal deposition (LMD) parts is one the main drawbacks this additive manufacturing technology that prevents direct use without implementation costly and time consuming post-processes. An in-process finishing operation need auxiliary equipment highly appealing to overcome such issues. For reason, re-melting performed with same used for process a promisin...

362 Abstract—In this study, the sorption behaviour of natural (clinoptilolite) zeolites with respect to cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) has been studied in order to consider its application to purity metal finishing wastewaters. The batch method has been employed, using competitive sorption system with metal concentrations in solution ranging from 50 to 300 mg/l....

Stainless steels, Ni-based alloys, Ti-based and more recently high entropy alloys have been used in the aerospace industry to improve exterior properties of components coatings that require a fine surface finishing with over temperature range. High- (HEA) become ground-breaking research field provides solutions for structural/ functional materials industry. These fabricated via direct metal dep...
