Abstract
Способ борирования стальных деталей, включающий приготовление насыщающей шихты с активатором (например, фтористым натрием), упаковку деталей в тигле, наведение на тигле плавкого затвора и термообработку с выдержкой в печи при температуре 800-950°С отличается тем, что в качестве борсодержащего компонента используется борная кислота, восстановление борной кислоты осуществляется в процессе химикотермической обработки в гранулах, вводимых в насыщающую шихту в количестве 20-40 мас.%, гранулы получают дроблением спекающейся при обезвоживании композиционной смеси борной кислоты, восстановителя (например, алюминия) и активатора первоначально содержащей:70-74 мас.% HBO+ 24-28 мас.% Al + 2 мас.% NaFв качестве разделительной добавки могут использоваться инертные порошки, например окись алюминия или окись магния, отработанные составы для борирования и др. смеси для получения комплексных боридных покрытий.The method of boron steel parts, including preparing a saturating charge with an activator (for example, sodium fluoride), packing parts in a crucible, inducing a fusible shutter on a crucible and heat treatment with holding in an oven at a temperature of 800-950 ° С differs in that it is used as a boron-containing component boric acid, the recovery of boric acid is carried out in the process of chemothermal treatment in granules introduced into the saturating mixture in an amount of 20-40 wt.%, granules are obtained by crushing sintering during dehydration a positional mixture of boric acid, a reducing agent (for example, aluminum) and an activator initially containing: 70-74 wt.% HBO + 24-28 wt.% Al + 2 wt.% NaF inert powders, for example alumina or magnesium oxide, can be used as a separation agent , spent compositions for boronization and other mixtures for complex boride coatings.
