Influencia De La Adición De Cobre En La Corrosión Del Cromado Metálico Para Aplicaciones En La Industria Automotríz

At present the use of metal coatings in the automotive industry is a priority so the present research had the objective of conducting studies of metallic chromium on surfaces of rings for buses applying national and international standards. The parameters of the coating process (time, temperature and voltage) are varied to check its incidence in corrosion by checking properties such as adhesion, hardness and layer thickness. It was determined that the optimum parameters for a nickel-chromium process are 60 min, 400 C and 7V, but with low corrosion resistance, so that an alternate coating was developed to add an alkaline copper layer, obtaining three layers, copper- nickel-chromium, thereby increasing corrosion resistance.

Metal coating without electrical energy using usually could be the conversion coating technique. One method of the conversion coatings that are widely used in the industrial field is blackening or black oxide coating. Blackening or black oxide coating technique is a chemical conversion process that is formed from the chemical reaction between the iron in ferrous metals by an oxidizing salt to form a layer of magnetite (Fe3O4) thin metal substrates. The metal coating process has a lot of choices to improve the quality of materials from metallic and nonmetallic. This study aims to investigate the effect of the time and the temperature of the heating process of the steel AISI 1015 on the thickness and the value of the glossiness level by the blackening processing technique. The research variables are used various heating process time: 30; 60; and 90 minutes, temperature: 100 °C; 150 ºC and 200 ºC, and other variables are controlled constantly. The workpieces made from a steel metal plate AISI 1015 has a dimension size = 200 x 30 x 3 mm3 in 27 pieces. The experimental method was designed by formation 3 x 3 x 3. It could be revealed the longer the healing process time could increase the thickness of the layer of the workpiece surface. A higher heating temperature could decrease the value of the glossiness level of a metal surface. The surface layer thickness level is found the best in the plating process time about 90 minutes and a temperature of 200ºC with a coating thickness values of 20,27μm. The highest value of the glossiness level is obtained at the highest coating time of 30 minutes at a temperature of 100ºC with the value of the shiny level of about 68.50 GU.
