ASSESSMENT OF A POSSIBILITY POLISHING OF STAINLESS STEELS JET ELECTROLYTIC AND PLASMA PROCESSING

Abstract

The possibility of jet electrolytic and plasma polishing of a surface of stainless steels is shown. Advantages of this type of processing in comparison with processing of products in an electrolytic bathtub are shown. The purpose of work is clarifica- tion of conditions under which there is a polishing of a surface of stainless steel at its processing by different cathodic modules. Tasks of work are assessment of volts - the ampere characteristic, the choice of electrolyte for polishing, the choice of range of the technological modes. As an object of researches samples and products are chosen from stainless steels 20X13, 08X18H9T, AISI 201. Polishing of products and samples from stainless steel was carried out on skilled jet electrolytic and plasma installa- tion. As cathodic modules were used hollow токоподвод and токоподвод equipped with a magnetron raspylitelny head. At a research of influence of electrolytic plasma on a surface of a product of the anode which is carrying out a role electrolyte on the basis of ammonium of sulfate and sodium sulfate has been used. In the course of carrying out numerous experiments are re- corded volt - the ampere characteristics electrolytically - the plasma category with use of different types of tokopodvod in the range of working voltage from 0 to 500 volts. In the course of the experiments the electrolyte consumption on all modes was fixed. Methods of macroshooting and microfilming of process electrolytically - plasma processing were used. Change of parame- ters of the plasma category with increase in tension is recorded. The morphological analysis of a surface of the processed an- ode after technological operation of a pileniye is carried out. Dependences of change of roughness on size of the enclosed ten- sion are investigated. It is carried out the analysis of change of weight of the samples making an anode role before electrolytic and plasma processing. The possibility of application of electrolytic and plasma jet processing as method of finishing processing for receiving a surface with the low level of roughness is shown.
