Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbomachine rotor blade with an outer part at its distal end.SOLUTION: The outer part comprises: a platform that defines an outside surface of a passage for gas passing through the turbomachine and has first and second opposite side edges; and upstream and downstream sealing wipers extending outwards from the platform, each wiper extending between two lateral faces situated respectively at the first and second side edges. The lateral faces of the upstream and downstream wipers are covered at least in part in an anti-wear material.SELECTED DRAWING: Figure 2 【課題】その遠位末端に外側部品を有するターボ機械ロータブレードを提供する。【解決手段】外側部品は、ターボ機械を通るガスの通路の外部表面を画定し、第一および第二対向側縁を有する、プラットフォームと；前記プラットフォームから外側に延在する上流および下流封止ワイパーであって、各ワイパーは第一および第二側縁にそれぞれ位置する２つの側面の間に延在する、上流および下流封止ワイパーとを含む。上流および下流封止ワイパーの側面は、少なくとも部分的に耐摩耗性材料で覆われている。【選択図】図２
