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.

A method includes depositing a first layer of a first material onto a surface of a chamber component of a processing chamber. The first material comprises a polymer, the polymer having a dielectric strength of at least 40 MV/m. The method further includes depositing a second layer of a second material onto the first layer. The second material comprises a first ceramic material impregnated into the first polymer or a second polymer. The method further includes depositing a third layer. The third layer is of a third material. The third material includes the first ceramic material or a second ceramic material. The third material does not adhere to the first polymer or the second polymer. The third material does adhere to the first ceramic material or the second ceramic material of the second layer.

The present invention is directed to methods for formation of refractory carbide, nitride, and boride coatings without use of a binding agent. The present invention is directed to methods of creating refractory coatings with controlled porosity. Refractory coatings can be formed from refractory metal, metal oxide, or metal/metal oxide composite refractory coating precursor of the 9 refractory metals encompassed by groups 4-6 and periods 4-6 of the periodic table; non-metallic elements (e.g. Si & B) and their oxides (i.e. SiO.sub.2 & B.sub.2O.sub.3) are also pertinent. The conversion of the refractory coating precursor to refractory carbide, nitride or boride is achieved via carburization, nitridization, or boridization in the presence of carbon-containing (e.g. CH.sub.4), nitrogen containing (e.g. NH.sub.3), and boron-containing (e.g. B.sub.2H.sub.6) gaseous species. Any known technique of applying the refractory coating precursor can be used. The porosity of resultant refractory coatings is controlled through compositional manipulation of composite refractory coating precursors.

A method of improving a structure of a component adjacent a feature is provided including removing a portion of the structure including at least one area where damage of corrosion has occurred or is likely to occur to expose a surface of the structure. A masking plug is installed into the feature such that a base of the masking plug is coupled to a first portion of the feature and a head of the masking plug is arranged adjacent a second portion of the feature. A structural deposit is formed on the surface and is integral with the structure. Excess material of the structural deposit and a portion of the head of the masking plug is removed. The second portion of the feature is reformed and the masking plug is removed from the feature.

An example hydraulic system component of a machine includes a protective coating deposited by high velocity air fuel (HVAF) thermal spray, exhibiting high adhesion strengths and surface morphologies that promote lubricant adhesion and reduce the leakage of oil and/or hydraulic fluid from the hydraulic system. The coating may have surface roughness with Rz values less than 2 μm and hardness of 1000 Vickers or greater. The HVAF coating may be thinner than conventional coatings with thicknesses less than 100 μm. The HVAF coating may be deposited on a variety of steel components with adhesion strengths greater than those achieved by high velocity oxygen fuel (HVOF). The HVAF coating may be formed without time consuming roughening and/or post-grind operations, resulting in cost savings compared to conventional coatings. The coatings may have operational lifetimes of 1000 hours or more.

A welding process involves a fixture for holding a workpiece and a welder, or welding electrode. The fixture imposes ultrasonic vibration on the workpiece. The welder vibrates during vibration, and is operable at a first voltage for welding and a second voltage for peening. The peening may occur while the weldmetal is crystallizing. The welding process may be a process of welding two part as together, or of filling a groove or other feature, or of applying or restoring a surface, or of applying a hard facing or ceramic to a parent metal or object. The weldmetal may be the same, or substantially the same, as the parent metal, or it may be different. The different material may be a ceramic material.
