Mathematical model of boride coats obtaining process at induction heating

Experimental studies of obtaining processes of boride coats of Fe-B-FenB composition are conducted at induction heating of samples from 65Mn steel. Coats intend for increase of wear resistance of working bodies of agricultural machines. Coats were received from a plastering on the basis of the powder mixes containing B4C (5-20 mas. %) and P-0,66 fused flux for a deposition.Проведены экспериментальные исследования процессов получения боридных покрытий состава Fe-B-FenB при индукционном нагреве образцов из стали 65Г. Покрытия предназначаются для повышения износостойкости рабочих органов сельхозмашин. Покрытия были получены из обмазок на основе порошковых смесей, содержащих B4C (5-20 мас. %) и плавленый флюс для индукционной наплавки П-0,66

Optimization of the design and technological parameters of an active ripper of a combined working body

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation
