Metal protective coatings have a number of advantages, including high corrosion resistance, resistance to mechanical stress, and attractive appearance. The article analyzes the requirements for technological equipment for chemical nickel plating of items made of carbon steels, aluminum, titanium, copper and their alloys. The disadvantages of standard equipment (chemical nickel-plating units functioning as separate technological units) during its operation as a part of a plating line are formulated. The results of modernization and design development for an improved unit for chemical nickel plating of metal products with repeated use of the plating solution are presented. The calculation of the walls’ strength, thermal calculation of tubular electric heaters, the calculation of a single-side suction without blowing with a suction gap in the horizontal plane were performed. Pneumatic cylinders with the required working force and stroke were selected. The modernized unit is more compact, easier to maintain, and its design allows it to function as a part of a plating line. Testing of the unit in a plating section of a real manufacturing facility showed its high efficiency.
The paper presents the results of the analysis of the requirements for process equipment for chemical nickel plating of metal products, including carbon steels, titanium, aluminum and their alloys. The disadvantages of standard equipment (UKhN series installations, functioning as a separate process unit) during its operation as part of a galvanic line are listed. The results of the design development of an improved installation for chemical nickel plating of metal products with repeated use of the solution are presented. The testing of the installation under the conditions of a galvanic section of a real mechanical production has shown its high efficiency.
