Abstract:
he occurrence of defects and the degree of incidence of cast during production of light alloy wheels by the method of low-pressure die casting depends on a large number of factors. One of the most frequent and difficult to detect (without destructive testing) defects is the turning of oxide spot. Its causes may include a wide range of variations in the composition of the raw materials, technology of alloy preparation and casting conditions. The negative impact on the product quality increasing amount of defective goods and economic losses. Solution to the problem is to use a special release coating with prescribed physicochemical properties. An experiment with coatings was carried out under production conditions, the cast weight - 12.5 kg.
