However, thermal diffusion treatment of pre-nickel-plated carbon steels with these compositions does not allow them to receive diffusion layers with a high corrosion resistance due to the unsatisfactory quality of the surface of the processed materials after chemical-thermal treatment.

Сравнительные данные по коррозионной стойкости предварительно никелированной Ст. 20 в 10%-ном раство- . ре фосфорной кислоты при использовании известного и предлагаемого составов приведены в таблице.The 12 distal steels after treatment in a known composition are not sufficient for the operation of parts from these matrices in highly aggressive chemical, petroleum and food products. The aim of the invention is to increase the corrosion resistance of processed products in phosphoric acid. This goal is achieved in that the powdered composition for chromosilicating nickel-plated carbon steel products, including aluminum oxide, chromium oxide, aluminum, silicocalcium, and ammonium chloride, additionally contains tungsten oxide and magnesium oxide in the following ratio of components,% by weight:. Magnesium oxide 2-4 Chromium oxide 34-36 Aluminum 6.5-8., 5 Silicocalcium 5.38-6.37 Tungsten oxide 1.12--2.13 - Ammonium chloride 1-3 Aluminum oxide Rest Chromosilicon in the proposed powder the medium is carried out for 4 hours in containers with a fusible closure. Comparative data on the corrosion resistance of pre-nickel-plated Art. 20 in 10% solution-. of phosphoric acid when using the known and proposed formulations are given in the table.
