A tooling for wheel spraying reinforcement can uniformly apply a hard coating on the inner rim and the spoke back cavity of a wheel, and can effectively solve the technical problems of uneven spraying and poor roundness. The high-precision spraying of the hard coating of the wheel is realized, and the device has novel structure, advanced technology and high universality.

Disclosed is a method for extending service life of a sacrificial-layer-free aluminum alloy wheel by laser shock, comprising: performing finite element analysis each position of the wheel under actual working conditions; connecting the to-be-peened wheel to a fixture on a robot; determining laser shock peening parameters; upon laser shock, performing cleaning treatment on the shocked wheel to remove surface ablating; and performing paint spraying treatment on the processed aluminum alloy wheel. The method provided by the present disclosure can not only improve surface hardness of the aluminum alloy wheel, but also form a residual compressive stress layer on a subsurface, thereby restraining crack propagation, prolonging the service life of an aluminum alloy wheel hub and improving stability of the hub.

A vehicle wheel includes a face portion including a central portion defining a Wheel axis and a plurality of spokes extending radially outwardly from the face portion. A rim portion circumscribes the wheel axis and is interconnected to the face portion by the plurality of spokes. The face portion and the rim portion define a first surface and a second surface. The first surface includes a paint finish defining a first gloss rating and the second surface includes a paint finish. defining a second gloss rating that is different than the first gloss rating presenting a multi-gloss paint finish to the wheel.

A device for masking securing boreholes in rims with masking elements having a storage container for the masking elements, a pressure generation unit, a connection unit connected to the storage container and an at least substantially tubular discharge device, which is secured at one end to the connection unit and which has a discharge opening at the opposite end for discharging the masking elements. The discharge device has a tube wall in which a channel for conducting a fluid is formed, the channel being connected to the pressure generation unit. The tube wall consists at least partially of an elastic material, through which the channel runs or in which a cavity connected to the channel is formed, such that, when the pressure of the fluid is changed, the tube wall deforms and releases the clamping on the masking elements. The connection unit and the discharge device are formed preferably as one piece in a 3D printing method.

A fishing component includes a first end portion, a second end portion and an intermediate portion extending between the first and second end portions. The first end portion has a surface on which a first dye is disposed. The second end portion has a surface which is free of the first dye or on which the first dye is disposed with a smaller amount than the first dye disposed on the surface of the first end portion. The intermediate portion includes a gradation portion having a surface on which the first dye decreases in amount from the first end portion toward the second end portion. The gradation portion has a length greater than or equal to 20 mm in a dye gradation direction extending from the first end portion toward the second end portion.

A method for applying a protective coating to a wheel hub unit includes mounting the wheel hub unit on a platform and applying a layer of the protective coating to a front surface of a mounting flange of the wheel hub unit. A shield covers a central annular portion of the front surface of the wheel hub unit to protect the central annular portion from the layer of protective coating, which can damage markings and magnetic components formed on the central annular portion. A handling arm attaches to the shield to hold the shield in place an axial distance away from the central annular portion of the front face.

A vehicle component with a multi-layer paint system and a method for producing the same. The vehicle component has a multi-layer paint system applied to a base body of the vehicle component. The multi-layer paint system has at least a first color-giving coating layer and a second color-giving coating layer covering the first color-giving paint layer. The first color-giving coating layer and the second color-giving coating layer are separated from each other by a light-permeable intermediate coating layer. The second color-giving coating layer is removed in partial areas of the multi-layer paint system, such that the first color-giving coating layer is visible in these partial areas.

A plasma vapor deposited (PVD) coating method. The method includes overlaying a primer polymer layer onto a substrate surface. The method further includes overlaying a chrome metallic layer onto the primer polymer. The method also includes depositing a plasma vapor deposited (PVD) oxide layer of a thickness of 1 to 5 nanometers onto the chrome metallic layer and having a parameter of color change of the underlying chrome metallic layer. The color change may be determined according to the following equation:
E*.sub.ab={square root over ((L*).sup.2+(a*).sup.2+(b*).sup.2)}
L is the color brightness of the oxide layer, and a and b are the color-component dimensions of the oxide and metallic layers. E*.sub.ab may be less than 2.3. The method further includes overlaying an exposed polymeric layer onto the PVD oxide layer to form a protective layer at the interface between the exposed polymeric layer and the oxide layer.

The present invention relates to a method for coating light alloy rims, to coating materials for use in this method, and to the coated light alloy rims obtained in this way. A primer layer, a base coat layer, and a clear coat layer are applied to a machined light alloy rim blank. The primer layer includes a radiation-curable coating material having an acid number of 10 to 120 mg KOH/g. The clear coat layer has a double-bond density of free-radically polymerizable reactive groups per unit mass of coating material of at least 1 mol/kg. The coating materials can be cured by radiation.
