A home appliance includes a hairline. A manufacturing method for a home appliance including a hairline includes forming at least one plating layer on a base material; processing a transverse hairline on an upper surface of a plating layer by tilting a hairline processing wheel at a predetermined angle, and forming a coating layer on the hairline. A home appliance having corrosion resistance and anti-fingerprint properties is produced while generating a transverse hairline. In addition, it is possible not to perform a separate plating after hairline processing.

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 R.sub.Z values less than 2 m and hardness of 1000 Vickers or greater. The HVAF coating may be thinner than conventional coatings with thicknesses less than 100 m. 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.

The present invention is intended to provide a roll-bonded laminate, in which an ultrathin metal layer is laminated on another metal without generation of wrinkles, cracks and the like.

A roll-bonded laminate formed by lamination of at least three layers, which comprises a peelable carrier layer 10, an ultrathin metal layer 20 and a metallic foil 30, wherein the thickness of the ultrathin metal layer 20 is 0.5 m or more and 20 m or less.

The present invention provides a Cr-rich cathodic arc coating, an article in turbine blade coated with the chromizing over cathodic arc coating, and a method to produce the coating thereof. The Cr-rich cathodic arc coating in the present invention comprises a cathodic arc coating and a diffusion coating deposited atop the cathodic arc coating to enforce hot corrosion resistance. The hardware coated with the chromizing over cathodic arc coating in the present invention is reinforced with superior-hot corrosion resistance. The present invention further provides a novel method for producing the chromizing over cathodic arc coating by re-sequencing coating deposition order. The method in the present invention is efficient and cost-reducing by eliminating some operations, e.g., DHT and peening, between the cathodic arc coating and the diffusion coating. The hot corrosion resistance in the present invention results from the high Cr content in the surface of the coating.

A process of fabricating a shield, a process of preparing a component, and an erosion shield are disclosed. The process of fabricating the shield includes forming a near-net shape shield. The near-net shape shield includes a nickel-based layer and an erosion-resistant alloy layer. The nickel-based layer is configured to facilitate secure attachment of the near-net shaped to a component. The process of preparing the component includes securing a near-net shape shield to a substrate of a component.

This invention relates to thermal spray coatings and processes onto non-smooth surfaces. The coating and processes can coat non-smooth surfaces without substantial degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The ability for coating fractional coverage to maintain the surface profile while maintaining wear resistance is unprecedented by conventional thermal spray processes.
