The present disclosure relates to a method for forming a parting line in a coating using an easily peelable coating material. The method includes: (i) attaching a masking tape to a part not to be coated on a boundary between a part to be coated and the part not to be coated along the boundary; (ii) performing a process to improve an adhesiveness with an easily peelable coating material on surfaces of a part in contact with the boundary of the part to be coated and/or a part in contact with the boundary of the masking tape; (iii) applying the easily peelable coating material over surfaces of the part to be coated and the part in contact with the boundary of the masking tape; and (iv) peeling off the masking tape.

A method and system for nanoscale precision programmable profiling on substrates. Profiling material is dispensed on a substrate or a superstrate. The superstrate is brought in contact with the substrate. The profiling material is then cured after bringing the superstrate in contact with the substrate. The superstrate is separated from the substrate after curing. An optical metrology of points on the substrate corresponding to the final substrate profile is then performed.

A method for improvement of adhesion and distribution along the surface of coatings using a femtosecond laser is described. The process starts from chemical preparation or cleaning of the target material, surface predetermination, laser irradiation of the surface until a certain surface geometry is obtained, which gives the surface improved wetting properties and chemical surface activation which results in improved adhesion of the coatings on the target material surface. The surface geometries and dimensions to be obtained during irradiation are selected according to the properties of the coating and target material, including the laser parameters and/or the environment to obtain the desired surface geometry, considering possible geometry errors without compromising essential adhesion.

A process for coating parylene onto a metal surface, such as a medical device, that has been textured by a series of laser pulses. The laser pulses can be overlapping or rastered. The textured portion of the metal surface and parylene coating can form a strong mechanical interlock. The bond created by using the laser texturing process can result in a cohesive failure of the parylene and not an adhesive failure of the bonding.

The plated sheet plate includes: base steel; a Zn—Mg plating layer formed on the base steel; and a UV-curable film layer formed on the Zn—Mg plating layer, wherein a hairline pattern is formed on a surface of the Zn—Mg plating layer, and the Zn—Mg plating layer includes 8 to 27 weight % of Mg and a balance of Zn and inevitable impurities.

A nanosecond laser ablation and chemical thermal decomposition for preparing a super-hydrophobic micro-nano structure on stainless steel. The method solves the defects of long preparation cycle and complex process flow of a super-hydrophobic surface of stainless steel, and does not use fluorine-containing chemical reagents for modification. The method includes: ultrasonically cleaning a stainless steel sample piece in absolute ethanol and air-drying at room temperature; performing primary infrared nanosecond laser ablation on the sample piece to obtain a micro-nano structure; evenly coating a surface of the workpiece with micro-droplets of a stearic acid ethanol solution by using an ultrasonic atomizer; performing secondary infrared nanosecond laser ablation on the sample piece; and ultrasonically cleaning the sample piece with acetone, absolute ethanol, and deionized water respectively for 10 minutes to remove undecomposed stearic acid and slag, thereby obtaining a stainless steel super-hydrophobic surface with stable super-hydrophobic property and good quality.

This disclosure relates to a method for obtaining superhydrophobic corrosion-resistant coatings. State-of-the-art approaches involve etching methods with elevated temperatures and/or longer duration which are complex and use high concentration of combination of acids, alkali, and salt solutions in etching process to obtain a roughness which makes it difficult to handle usage of chemicals and controlling process. The method of the present disclosure has addressed this issue by selection of optimum concentrations of combinations of one or more type of acids, oxidizing agents which are safe, easy to handle and provide better control over the process. The method of the present disclosure is easy, inexpensive, and environmentally friendly. The superhydrophobic corrosion-resistant coatings possess water contact angles greater than 151° and coating efficiency more than 85 percent arrived at by using corrosion currents from polarization studies.

Embodiments of a system, method and apparatus for a gear are disclosed. For example, a metallic gear hub can include an axis of rotation and metallic gear teeth. The metallic gear teeth can be smaller than a final gear teeth size of the gear. The metallic gear teeth can be co-planar with the axis. In addition, the metallic gear teeth can be non-orthogonal to the axis. A polymer layer can be located on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth. The polymer gear teeth can form the final gear teeth size of the gear.
