Methods and systems for treating components are described. The methods include using a system having a controller, a laser applicator, a coating applicator, and a sensor array. The laser applicator, the coating applicator, and the sensor array are arranged on a treatment arm that is controlled by the controller. The method includes scanning a surface to be treated of the component using the sensor array, cleaning the surface to be treated using the laser applicator, defining surface texture patterns, applying laser texturing, and applying a new coating to the surface to be treated using the coating applicator.

A method for applying an abrasive comprises: applying, to a substrate, the integral combination of: a self-braze material; and an abrasive embedded in the self-braze material; and securing the combination to the substrate.

Abrasive preforms and manufacture and use methods

An abrasive sheath for application to a component surface is disclosed. The abrasive sheath may comprise a metallic layer and an abrasive layer plated on a surface of the metallic layer. The abrasive layer may include a metal matrix and abrasive particles protruding from the matrix. An exposed surface of the metallic layer of the abrasive sheath may be joinable to the component surface by a heat treatment.

Abrasive sheathing

A method for repairing a blade wherein the blade comprises a metallic substrate shaped to define an airfoil having a tip. A coating is on the tip. The method comprises: machining to at least partially remove the coating; plating a nickel-based base layer; and plating an abrasive layer comprising a nickel-based matrix and an abrasive.

Turbine blade tip repair

A method for applying an abrasive comprises: applying, to a substrate, the integral combination of a self-braze material, an abrasive, a matrix in which the abrasive is at least partially embedded, and an intermediate layer between the self-braze material and the matrix; and heating to cause the self-braze material to braze to the substrate.

Abrasive coating and manufacture and use methods

A method for applying an abrasive comprises: applying, to a substrate, the integral combination of: a self-braze material; an abrasive; and a matrix in which the abrasive is at least partially embedded; and heating to cause the self-braze material to braze to the substrate. The heating leaves at least a portion of the self-braze material with a composition comprising, in weight percent: cobalt 2.5-13.5; chromium 12-27; aluminum 5-7; yttrium 0.0-1.0; hafnium 0.0-1.0; silicon 1.0-3.0; tantalum 0.0-4.5; tungsten 0.0-6.5; rhenium 0.0-2.0; molybdenum 0.1-1.0; and the balance nickel.

The present disclosure relates generally to strip process for removing a coating from a substrate comprising the steps of: providing a base alloy and a MCrAlY coating deposited over the base alloy substrate; and removing the MCrAlY coating by bringing the MCrAlY coating in contact with an acid solution comprising nitric acid, phosphoric acid and ammonium bifluoride in an aqueous solution, and maintaining the acid solution contact for sufficient time and at sufficient temperature to permit the coating to be stripped from the base alloy substrate.

A media blast includes a nozzle body manufactured of a first material with a set of internal threads manufactured of a second material different than the first material. A media blast nozzle for a spray gun, the media blast nozzle includes a nozzle body manufactured of a first material, the nozzle body defines an axis; and an insert with a set of internal threads manufactured of a second material different than the first material, the insert located at least partially within the nozzle body.

Media blast nozzle with non-metallic threads

A stripping solution comprises a highly corrosive acid and an iron concentration of at least about 1.0 gram per liter (g/L). The stripping solution is air agitated to remove a coating from a metal article submerged therein.
