METHOD FOR SURFACE BORATION OF PARTS FROM STEEL 40
FIELD: metallurgy.SUBSTANCE: first, preliminary local surface boration is performed using laser heating from a coating material containing boron or its compounds. Then, thermodiffusion boron saturation process is performed at heating to the temperature T=850-950°C with exposure during 3-4 hours.EFFE...

| description | FIELD: metallurgy.SUBSTANCE: first, preliminary local surface boration is performed using laser heating from a coating material containing boron or its compounds. Then, thermodiffusion boron saturation process is performed at heating to the temperature T=850-950°C with exposure during 3-4 hours.EFFECT: reduction of brittleness of borated layers; reduction of duration and temperature of a thermodiffusion saturation process of surface of parts at maintaining high hardness.1 tbl
Изобретение относится к области металлургии и машиностроения, а именно к комбинированным способам поверхностного упрочнения деталей из стали 40. Первоначально проводят предварительное поверхностное локальное борирование с использованием лазерного нагрева из обмазки, содержащей бор или его соединения. Затем осуществляют процесс термодиффузионного насыщения бором при нагреве до температуры Т=850-950°С с выдержкой в течение 3-4 часов. Обеспечивается снижение хрупкости борированных слоев, сокращение длительности и снижение температуры процесса термодиффузионного насыщения поверхности деталей при сохранении высокой твердости. 1 табл. |
