摘要： A method of producing layers of lead and its alloys on workpieces made of ferrous alloys comprising dipping the workpieces to be coated into a two-layer bath, the upper layer of which is a bath of aluminum or its alloys, and the bottom layer of which is a bath of lead or its alloys. The workpieces are then taken out of the deeper layer of the bath of lead and its alloys by pulling them through the upper layer of the bath of aluminum and its alloys, or by pulling the workpieces through the bath of metal, provided in a vessel connected with the bottom layer of the bath.The temperature of both baths, the upper bath and of the bath in the vessel connected with the bottom bath, is maintained within the range of 150.degree. C to 900.degree. C. The temperatures of the bath of the upper layer, of the bath of the bottom layer, and of the bath in the vessel connected with the bath of the bottom layer are equal or differ from each other by 50.degree. C to 750.degree. C.

摘要： The work-pieces are mechanically cleaned, degreased and washed, and then etched in an aqueous solution containing 0.5-1.0% by weight of citric acid, and 16-24% by weight of hydrochloric acid, having a temperature of 15.degree.-30.degree. C., preferably of 20.degree.-25.degree. C., for the time of 1-20 minutes, preferably 2-5 minutes, whereafter the work-pieces are neutralized in an aqueous ammonia solution having a concentration not exceeding 1% by weight, at a temperature of 15.degree.-25.degree. C., in a time not shorter than 1 minute. After being washed in water at a temperature not exceeding 35.degree. C. in a time not shorter than 1 minute, they are dipped in an agitated aqueous solution of the flux, containing 1.8-2.5% by weight of potassium fluoride, 0.8-1.5% by weight of sodium fluoride, and 1.5-3.0% by weight of potassium fluorozirconate, having a temperature of 40.degree.-80.degree. C. After at least two minutes of holding in the flux, the work-pieces are dried and finally dipped in a melt of aluminum or alloys thereof. Alternatively a flux having composition 1.5-2.0% by weight of potassium fluoride, 1.5-2.0% by weight of sodium fluoride, 6.0-10.0% by weight of sodium tetraborate and 2.5-5.0% by weight of acetic acid, having a temperature of 15.degree.-40.degree. C. may be used, for a period not shorter than 2 minutes.
