A propeller blade comprises a fibre reinforced blade structure spar having a blade retention section formed at one end thereof, and at least one metallic formation spray deposited onto said blade retention section.

A composite layer system is presented. The composite layer system includes a metallic substrate, a structured surface, and a thermal protection system. The structured surface may be additively manufactured onto the metallic substrate and includes structured surface features formed to project above the metallic substrate. Each of the structured surface features are separated from adjacent structured surface features by grooves. The thermal protection coating may be thermally sprayed onto the structured surface and is bonded to each of the structured surface features.

Provided is a processing component of equipment for manufacturing a semiconductor or a display. A ceramic coated film is formed on a surface of a body of the processing component, in a state in which some or the entirety of valleys and peaks are removed, such that a surface roughness Rz, which is expressed as an absolute value (P1+P2+P3+P4+P5)/5−(V1+V2+V3+V4+V5)/5 corresponding to a difference between an average of distances between the deepest five valleys V1, V2, V3, V4 and V5 in a section in which the surface roughness is measured and an arbitrary datum line that is parallel to a center line at which an area of peaks and an area of valleys are equal to each other in the section in which the surface roughness is measured and an average of distances between the highest five peaks P1, P2, P3, P4 and P5 in the section in which the surface roughness is measured and the arbitrary datum line, is lower than 5.0 μm.

In one example, a method for forming a coating system including a bond coat and an environmental barrier coating on a ceramic or CMC substrate, e.g., with an abradable coating on the environmental barrier coating. The method may include depositing a bond coat on a ceramic or ceramic matrix composite (CMC) substrate to form an as-deposited bond coat; heat treating the as-deposited bond coat following the deposition of the as-deposited bond coat on the substrate to form a heat treated bond coat; depositing an environment barrier coating (EBC) layer on the heat treated bond coat to form as deposited EBC layer; and heat treating the as-deposited EBC layer to form a heat treated EBC layer.

A method for manufacturing a golf club head having an embedded heterogeneous material includes preparing a shell mold having a cavity and a functional member embedded into the shell mold via an embedded portion, filling the cavity with a metal liquid to completely dip the non-embedded portion of the functional member in the metal liquid; breaking the shell mold to obtain a cast product, separating the golf club head cast member from the cast product to obtain a semi-finished golf club head having a casting material and a heterogeneous material, and pressing the casting material of the semi-finished golf club head to securely engage the casting material with the heterogeneous material. The functional member includes a non-embedded portion connected to the embedded portion and located in the cavity. The cast product includes a golf club head cast member.
