ДИФФУЗИОННО-ЛЕГИРОВАННЫЕ СПЛАВЫ ИЗ МЕТАЛЛИЧЕСКИХ ОТХОДОВ ПРОИЗВОДСТВА С ПОНИЖЕННОЙ ТЕМПЕРАТУРОЙ ПЛАВЛЕНИЯ ДЛЯ ФОРМИРОВАНИЯ ИЗНОСОСТОЙКИХ ПОКРЫТИЙ ИНДУКЦИОННОЙ НАПЛАВКОЙ ТОКАМИ ВЫСОКОЙ ЧАСТОТЫ

Abstract

В работе рассмотрена технология получения диффузионно-легированных сплавов из металлических отходов производства и исследовано влияние предварительной кратковременной высокотемпературной обработки концентрированными источниками энергии на структурообразование при последующей индукционной наплавке токами высокой частоты. Предложен и описан механизм контактного эвтектического плавления в диффузионно-легированных сплавах при кратковременной высокотемпературной обработке. Установлена целесообразность данной обработки для диффузионно-легированных сплавов при формировании износостойких покрытий индукционной наплавкой токами высокой частоты. Предложена комплексная ресурсои энергосберегающая технология получения износостойких покрытий из диффузионно-легированных металлических отходов производства индукционной наплавкой токами высокой частоты.

The technology of obtaining diffusion doped alloys made from metal scrap is reviewed in the article. The influence of short term preprocessing at high temperature on structure formation by concentrated energy sources within the further induction deposit is reviewed. A mechanism of a contact eutectic melting in diffusion doped alloys at short term high temperature treatment is described and suggested in this work. It was shown that such kind of processing of diffusion doped alloys is a perspective way of treatment when using induction hard-facing technologies for obtaining wear resistant coatings. A resource and energy saving technology was developed for obtaining wear resistant coatings based on diffusion doped alloys from metal scrap treated using induction hard-facing process.
