摘要： A method for balancing a rotor, notably of a turbomachine, includes a step of determining an unbalancing mass, and a step of balancing by chemical machining of the rotor. The chemical machining includes arranging a bath containing a chemical machining agent so that the bath has a capacity of heterogeneous material removal as a function of the depth in the bath, an amount of material removal at a first depth in the bath is greater than an amount of material removal at a second depth in the bath; immersing the rotor in the bath; and orienting the rotor in the bath taking account of the capacity of heterogeneous material removal so that the quantity of material removed from the rotor in a zone of the unbalancing mass is sufficient to balance the rotor.

摘要： A method for vapor phase deposition of a metal coating onto parts made of superalloys, which includes arranging the parts in a chamber in a presence of grains of a donor of the coating metal and an activator capable of together forming a halide of the coating metal, and heating the chamber under an inert gas or reducing gas atmosphere to a temperature at which the coating metal halide reacts with the alloy of the parts. A bed of the grains is arranged on the bottom of at least one box, then a mounting for the parts is placed on the bed of grains, the mounting including support columns that keep the parts separate from the bed of grains, and the gas is injected into the box, when the box is closed, via a side located above the bed of grains.
