A stationary shroud (24) of a gas turbine engine made of a base metal is repaired by removing any damaged material from a flow-path region (40) of the stationary shroud (24) to leave an initially exposed base-metal flow-path surface (70); and applying a base- metal restoration (72) overlying the initially exposed flow-path surface (70). The base- metal restoration (72) is applied by furnishing a source of a structural material that is compatible with the base metal, in a form such as a powder or a wire, and depositing the source of the structural material overlying the initially exposed base-metal flow-path surface (70) of the stationary shroud (24) by laser cladding to form a repaired base-metal flow-path surface (76). An environmentally resistant rub coating (78) may be applied overlying the base-metal restoration (72).
