This article is devoted to the formation of amorphous coatings on the steel 35 surface by electrospark treatment in a mixture of crystalline granules. It is revealed by the energy dispersive X-ray spectroscopy (EDS) that formed coatings contain W, Mo, Co, and Ni in various ratios. The weight of granules of various compositions decreases by 11–16 wt % for 6-h treatment due to electric erosion. The mass transfer coefficient varies in a range from 33 to 54%. X-ray structural analysis showed the prevalence of an amorphous phase (81–99%) in the structure of deposited layers. Annealing of coatings at a temperature above 1150°C leads to the crystallization of the amorphous phase into boron carbide of the M₂₃(C, B)₆ type, as well as into α-Fe. The coatings have an increased hardness of 10–15 GPa, while their wear resistance in the dry sliding wear mode under loads of 10 and 50 N is higher than for steel 35 by a factor of 3.3 and 1.6. The coating friction coefficient is lower than for steel 35 by 13–30% and was 0.27–0.31. The wear resistance of coatings in a dry abrasive wear mode is higher by a factor of 3–5 when compared with uncoated steel 35. The best characteristics are inherent without nickel and worst are inherent without cobalt. Thus, it is established that tungsten and cobalt increase the wear resistance of iron-based amorphous alloys, while nickel and molybdenum tend to worsen their tribotechnical behavior.

电火花处理在结晶颗粒混合物中沉积非晶态硬化涂层

本文致力于在结晶颗粒混合物中通过电火花处理在钢35表面形成无定形涂层。通过能量色散X射线光谱法（EDS）揭示，所形成的涂层包含各种比例的W，Mo，Co和Ni。对于6小时的处理，由于电腐蚀，各种组成的颗粒的重量减少了11-16 wt％。传质系数在33％至54％的范围内变化。X射线结构分析表明，在沉积层的结构中普遍存在非晶相（81–99％）。在高于1150°C的温度下对涂层进行退火会导致非晶态相结晶为M ₂₃（C，B）_6的碳化硼类型，以及成α-Fe。涂层的硬度提高了10-15 GPa，而在10和50 N的载荷下干滑动磨损模式下的耐磨性比35钢高3.3和1.6倍。涂层摩擦系数比35钢低13-30％，为0.27-0.31。与未涂层的钢35相比，干磨料磨损模式的涂层的耐磨性提高了3-5倍。无镍是固有的最佳特性，而无钴是固有的。因此，可以确定钨和钴增加了铁基非晶态合金的耐磨性，而镍和钼则倾向于使它们的摩擦学性能变差。
