Abstract

The presented results significantly expand the information on the modification of sputtered materials (PG-10K-01 + CrB2 or TiB2) in a plasma stream, which makes it possible to vary the operational parameters of the process for shaping the necessary structure of the protective layer with enhanced performance properties. Thus, if the parts are subject to impact loads, the preferred option is fused coatings in the form of gradient-layer composites. If the parts operate under ordinary abrasive friction, the fusion operation can be excluded from the production process provided that particles are ground during sputtering; in addition, an evenly strengthened coating structure is formed. New compositions of microcomposites for plasma sputtering of coatings are developed for being crushed in the plasma stream, which is followed by the spheroidization of dispersed components; this allows excluding the use of submicron powders during plasma sputtering for they are somewhat difficult to supply along powder-feeding lines and improving the wear resistance of the composites by 7.35–27.33%.

过渡金属硼化物增强的自熔性PG-10K-01合金等离子涂层的耐磨性

摘要

提出的结果极大地扩展了有关等离子流中溅射材料（PG-10K-01 + CrB2或TiB2）的改性信息，这使得改变工艺操作参数以形成必要的保护层结构成为可能。具有增强的性能。因此，如果零件受到冲击载荷，则首选选择是梯度层复合材料形式的熔融涂层。如果零件在普通的磨擦摩擦下工作，只要在溅射过程中将颗粒磨碎，就可以将熔化操作排除在生产过程之外；另外，形成均匀强化的涂层结构。开发了用于等离子体喷涂涂层的新型微复合材料组合物，以便在等离子体流中粉碎，随后是分散的组件的球化；这样可以排除在等离子溅射过程中使用亚微米粉末，因为它们很难沿粉末进料线供应，并且将复合材料的耐磨性提高了7.35–27.33％。
