Description

Изобретение относитс  к сварочному ироизводству и может быть применено в машиностроении , в частности в судовом. Известен способ наплавки поверхностноактивных металлов и сплавов па сталь с при- .5 менеиием термообработки стальной основы, требующий панесени  нромежуточного сло  ггутем нанлавки. Снижение проникновени  новерхноетно-активпых металлов в сталь и исключение на- ю плавки промежуточного сло  обеснечиваетс  тем, что в процессе нанлавкн в поверхностном слое стали создают поле сжимаюпшх папр жений путем охлаждени  термического вли ни  со скоростью, не меньшей 15 критической, онредел емой по диаграмме распада переохлажденного аустенита стали. Нап.тавка поверхностно-активных металлов и сплавов, например медных, на сталь, например 34ХНЗМ, производитс  с охлаждепием 20 зоны термического вли ни  со скоростью не менее 30°С/сек в интервале температур 700- 300°С. Стали мартенситного и перлитного классов могут быть также использованы в качестве подсло , например, при наплавке по- 25 ворхностпо-активных металлов и сплавов на стали аустенитного класса. Ирн этом дл  сннжеин  нропнкновени  новерхностно-активных металлов и снлавов в подслой скорость его охлаждени  при наплавке на него поверхностно-активных метал.шв и снлавов должна быть ire меньше критической скорости распада переохлажденного аустенита стали, котора  используетс  в качестве подсло . И р е д м е т н з о б р е т с и и   Снособ наплавк новсрхностно-актнв1Нз1х металлов и снлавов на сталь, нреимуп1,ественно нерлитного и мартенситного классов, с применением термообработки стальной основы, отличающийс  тем, что, с целью уменьшени  проникновени  новерхпостно-активных металлов в сталь и исключени  наплавки нромежуточного сло , в процессе наплавки в поверхностно .м слое стали создают ноле сжимающнх напр жений путем охлаждени  зоиы термического вли пп  со скоростью не меньшей критической, определ емой по диаграмме распада переохлажденного aycTeiniTa сталн.The invention relates to welding and production and can be applied in mechanical engineering, in particular in the marine industry. There is a method of surfacing surfactant metals and alloys on steel with the addition of heat treatment of the steel base, which requires the wood of the intermediate layer to be gutted nanowires. Reducing the penetration of supercurrent metals into steel and eliminating the melting of the intermediate layer is ensured by the fact that, in the process of nanlavinks, a compressive vapor field is created in the superficial steel layer by cooling the thermal effect at a rate not less than 15 critical according to the decomposition diagram supercooled austenite steel. The delivery of surfactant metals and alloys, such as copper, to steel, for example, 34HNZM, is carried out with cooling of the heat affected zone at a rate of at least 30 ° C / sec in the temperature range 700-300 ° C. Martensitic and pearlitic steel grades can also be used as a sublayer, for example, in the deposition of auxiliary metals and alloys on austenitic steel. For this purpose, for the deposition of surface-active metals and snlavs in the sublayer, the rate of its cooling during surfacing of surface-active metal shv and snlavs should be less than the critical decomposition rate of supercooled austenite steel, which is used as a sublayer. In addition, the method of surfacing modern metals and steel on steel, which is of the naturally non-marlite and martensitic classes, using heat treatment of the steel base, characterized in that, in order to reduce penetration of no-broom active metals into steel and elimination of surfacing of the intermediate layer, in the process of surfacing in the surface layer of steel, create a zero compressive stress by cooling the heat-affected zone at a rate not lower than the critical one determined by the decay diagram chilled aycTeiniTa stan.
