Abstract
Tooling for the coating of lips of a turbomachine rotor sector, comprising a support for a rotor sector, a centering plate adapted to be inserted into a rotor sector, said centering plate having a central housing, a tool, said tool comprising a centering arm, adapted to be inserted into the central housing of the centering plate, a torch, adapted to spray a ceramic material, a machining tool, said tooling being configured so as to position the tool relative to the rotor sector via the centering plate, and to simultaneously perform on the rotor sector a spraying of ceramic material and a machining on two distinct sectors of the lips.
Claims8
A tooling for coating lips of a turbomachine rotor sector, comprising a support for a rotor sector, a centering plate adapted to be inserted into a rotor sector, said centering plate having a central housing, a tool, said tool comprising a centering arm, adapted to be inserted into the central housing of the centering plate, a torch, adapted to spray a ceramic material, a machining tool, said tooling being configured so as to position the tool relative to the rotor sector via the centering plate, and to simultaneously perform on the rotor sector a spraying of ceramic material and a machining on two distinct sectors of the lips.
A method for forming an abradable coating for lips of a turbomachine rotor sector, the method comprising:
- providing the turbomachine rotor sector comprising a plurality of lips;
- positioning the rotor sector on a support;
- securing a centering plate to an open end of the rotor sector, and placing an opposite end of the rotor sector on the support, said centering plate having a central housing;
- positioning a tool relative to the rotor sector, by inserting a centering arm in the central housing of the centering plate, said tool being provided with a torch and a machining tool;
- driving the rotor sector in rotation relative to the tool;
- and
- actuating the torch to spray a ceramic material on the lips of the rotor sector, and positioning the machining tool to machine said lips parallel to the spraying of the ceramic material by the torch.
