Article

We evaluate the corrosion resistance of welded joints of sintered VT1-0 titanium obtained by convection friction welding according to the results of electrochemical and gravimetric investigations in aggressive media of inorganic acids (hydrochloric and sulfuric). It is shown that corrosion-resistance characteristics of the metal of the zone of thermomechanical influence are higher than for the base metal due to the formation of a more homogeneous structure, its refining, substantial increase in the density of the compacted material (decrease in the sizes and number of pores), and the absence of segregation of additives. The prospects of application of the method of pressure welding in manufacturing the products of chemical industry from sintered titanium are confirmed.
