Robotized GMA surfacing of cermetalic layers

摘要

AbstrAct Purpose: Purpose of these researches was to investigate of influence of heat input in robotized surfacing on quality and properties of cermetalic layers. Design/methodology/approach: The 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 it was used robotized surfacing stand, 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 wear plates it is needed to compare theirs properties with others presented technologies of wear plates producing. Practical implications: Results of this paper is to optimal range of parameters of surfacing of single and multilayer, stringer and weave beads of cermetalic layers. Originality/value: The researches (hardness 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.
