Description
Предложенный сплав относитс к области износостойкой наплавки.The proposed alloy is in the field of wear-resistant surfacing.
Известен износостойкий .наплавочный сплав, содержащий, %:Known wear-resistant. Alloy, containing,%:
углерод 5,5-8 хром 40-60 бор1-2carbon 5.5-8 chrome 40-60 bor1-2
железо остальноеiron else
С целью повышени износостойкости и твердости наплавленного метала, работающего в услови х абразивного износа и,воздействи агрессивных сред, в состав сплава введен кремний в количестве 0,7-1,4%, а остальные компоненты вз ты в следующем соотношении, %:In order to increase the wear resistance and hardness of the deposited metal, working under conditions of abrasive wear and exposure to corrosive media, silicon in the amount of 0.7-1.4% is introduced into the composition of the alloy, and the other components are taken in the following ratio,%:
хром 40-44 бор 0,7-8,5 углерод 0,01-5,0 железо остальноеchromium 40-44 boron 0,7-8,5 carbon 0,01-5,0 iron the rest
В состав сплава может быть введен углерод в количестве до 5%. Заниженное содержание кремни не создает опасности дл сплава, но в сочетании с 8,5% бора обеспечивает самофлюсование сплава при напылении.The composition of the alloy can be introduced carbon in an amount up to 5%. The low silicon content does not pose a danger to the alloy, but in combination with 8.5% boron, it provides for the self-fluxing of the alloy during deposition.
Высокое содержание хрома и бора необходимо дл получени износостойких наплавленных слоев, насыщенных боридами.A high content of chromium and boron is necessary to obtain wear-resistant weld layers saturated with borides.
Исходные компоненты в виде ферросплавов или металлов измельчают и смешивают до получени однородной смесн. Смесь просыпают через вертикальную трубчатую печь с 5 одновременным просеиванием через сито. В процессе свободного падени вдоль печи конгломераты, образовавшиес после просева порошкообразной смеси через сетку, расплавл ютс (т. пл. 1350°С) и под действием силThe starting components in the form of ferroalloys or metals are ground and mixed to obtain a homogeneous blend. The mixture is poured through a vertical tube furnace with 5 simultaneous sieving through a sieve. In the process of free fall along the kiln, the conglomerates formed after sifting the powder mixture through the grid are melted (mp 1350 ° C) and under the action of forces
поверхностного нат жени принимают сферическую форму.surface tension take a spherical shape.
Применение сфероидицированного порошка позвол ет наносить защитные слои от дес тых долей миллиметров до одного сантиметра сThe use of a spheroidized powder makes it possible to apply protective layers from tenths of millimeters to one centimeter with
