Applications Method of producing spray deposit on bearing boss. Prior to forming a thermal spray coating layer on an end face of a structural base material to be shaped into a boss, firstly an inner masking member is fitted in an original hole of the structural base material and then an outer masking member is fitted on outer peripheral side of the structural base material. In the next place, by the use of a hard material, a thermal spray coating layer is formed on an annular coating area which is exposed between the inner and outer masking members and. Surface areas on the end face of the structural base material, corresponding to an allowance range of a machining operation by which the original hole is ultimately shaped into a joint pin hole of a specified diameter, are left as a non-coating area free of the thermal spray coating layer. Therefore, the original hole in the structural base material can be machined into a final joint pin hole by means of a cutting tool, without experiencing cracking troubles which would otherwise occur to the thermal spray coating layer during the machining operation.

Ceramic abradable materials, in particular thermally sprayable ceramic abradable powder materials, and abradable seals formed by thermally spraying the materials include dysprosia (Dy2O3) and zirconia (ZrO2). Coatings are porous whereby the porosity, in part, is induced by plastic or fugitive phases. Abradable seal coatings com-

prising dysprosia and zirconia exhibit improved thermal shock and sintering resistance and can be worn into tolerance by untreated, bare turbine blades, at least in certain regimes of relative blade speed and coating porosity. Ceramic abradable seal coatings comprising dysprosia and zirconia can be used up to 1200 C. US 7981530: Dieter R. Sporer, Ulrike Taeck, Mitchell R. Dorfman, Andrew R. Nicoll, Massimo Giannozzi, and Iacopo Giovannetti. Company: Sulzer Metco (US), Inc. Issued/Filed: 2011-0719/2007-06-07. Method for treatment of a surface of a gas turbine engine component. The treatment process for the surface of an engine component involves preparing a treatment device including a highvelocity oxygen fuel (HVOF) burner with a nozzle or a cold gas spray device, and a powder containing ceramic, preparing the surface and blowing the powder over at least a sector of it using the HVOF burner or cold gas injection, moving it along the surface t
