the applications of electrochemical machining are increasing because of increasing requests of industries for materials with high strengh and high hardness. regular ecm uses a tool with spicified profile shape that is similar to final shape of workpiece. in this reasearch a nozzle that delivers electrolyte to the machining gap is used for machining cylinderical workpieces. by moving the electro...

In this work, we have studied the methods of electrochemical processing materials in order to give them new functional properties. Experimental data on production corrosion-resistant coatings based Zn-Ni and Zn-Co alloys from ammonium oxalate electrolytes study their protective properties are presented. The questions carbon nanomaterials by anodic exfoliation graphite sulfuric acid considered. ...

The tumour is treated by electrochemical treatment (ECHT) or electrolytic ablation neoplastic tissue with a continuous direct current through two more electrodes located inner side nearby the tumour. ECHT has been taken considerable attention as being one of numerous methods for malignancies local treatment. therapy benefit negligibly invasive procedure and few serious effects. Despite treating...

Abstract—A number of toxic chlorophenolic compounds are formed during pulp bleaching. The nature and concentration of these chlorophenolic compounds largely depends upon the amount and nature of bleaching chemicals used. These compounds are highly recalcitrant and difficult to remove but are partially removed by the biochemical treatment processes adopted by the paper industry. Identification a...

introduction             wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...
