Purpose: of this research was to investigate the influence of heat input in robotized surfacing on quality and properties of nanomaterial layers. Design/methodology/approach: quality of single and multilayer, stringer and weave beads was assessed by abrasion resistance tests according to ASTMG65 standard, erosion resistance tests according to G76 standard, metallographic examinations and hardness tests. Findings: due to the fact that the robotized surfacing stand was used, the analysis of properties of the deposits was performed for single and multilayer, stringer and weave beads. Research limitations/implications: for complete information about tested deposits it is needed to compare deposits properties PTA surfaced with other technologies of nanomaterial layers manufacturing products. Practical implications: Results of this paper is an optimal range of parameters of surfacing of single and multilayer, stringer and weave beads of nanomaterial layers. Originality: tests, abrasion and erosion resistance tests) were provided for surfacing of single and multilayer, stringer and weave beads, and the results were compared. The influence of heat input on layers properties and theirs structure was defined.
