Electron‐beam deposition (EBD) is an advanced technique intended for the formation of protective coatings that exhibit high strength and wear, and fatigue resistance. The investigation of the structure of coated materials and the development of mesoscale plastic deformation shows that these properties depend heavily on EBD modes. It is proposed that the latter can be optimized by: (i) choosing the electron‐beam parameters that ensure a uniform structure of the coating, appropriate width and proper structure of the transient zone, (ii) the trial‐and‐error method of selecting such deposited powder composition that ensure high strength properties, and (iii) mechanical test aimed at distinguishing the coatings whose performance has been advantageously increased by EBD.

“…Electron beam surfacing in vacuum is a good candidate to obtain a hard coating on the surface of low carbon substrate. Such a processing provides some advantages [1] which include the ability to feed composite surfacing powders directly to the melted pool, vacuum refinement of the melted metal, gradual and accurate adjustment of the electron beam power to provide both minimal fusion penetration to the substrate, constant chemical composition, and small pool's size at electron beam power density up to 10 5 W/cm 2 . All these parameters may be optimized to achieve the pool's overheating required to obtain over saturated solution of the alloying elements and fine-grain structures in cooling.…”

Features of phase-structure formation and abrasive wear resistance of composite coatings "WC-M2 steel" worn against tungsten monocarbide have been investigated. It was established that adding 20 wt.% WC to the deposited powder mixture leads to the increase in M 6 C carbide content. These carbides show a multimodal size distribution consisting of ∼5.9 μm eutectic carbides along the grain boundaries, ∼0.25 μm carbides dispersed inside the grains. Also a greater amount of metastable austenite (∼88 vol.%) is found. The high abrasive wear resistance of these coatings is provided by γ → α -martensitic transformation and multimodal size distribution of reinforcing particles.
