Description

372 параметров при об1заботке и соотношений компонентов в составе на скорость диффузионного насьпцени  представлены в табл , 1. Вли ние технологических параметров при обработке и соотношений компонентов в составе на свойства обрабатываемых деталей представлены в табл. 2 В результате цинкохромосилицировани  алюминиевого сплава , из предлагаемого состава поверхностна  тшфдость сплава по сравнению с исходным состо нием возрастает в 3-3t5 раза, а коррозионна  стойкость в ЗО%-ном водном растворе едкогр натра возрастает в 6-lb раз. Табл ица1.372 parameters during processing and ratios of the components in the composition for the diffusion rate are presented in Table 1. The effect of the technological parameters during processing and the ratios of the components in the composition on the properties of the parts being machined are presented in Table. 2 As a result of zinc chromosilication of an aluminum alloy, from the proposed composition, the surface alloy content increases by a factor of 3–3t5 compared to the initial state, and the corrosion resistance in an SO3% aqueous solution of sodium hydroxide increases by a factor of 6–1b. Table 1.
