A method of remanufacturing a fluid end block of a well stimulation pump includes cleaning an interior surface of a body of the fluid end block. The interior surface defines a chamber, a plunger passage in communication with the chamber, an intake passage in fluid communication with the chamber, and a discharge passage in fluid communication with the chamber. The interior surface is made from a base material. The interior surface of the fluid end block is cold-worked to produce a compressive residual stress layer within the body. A coating layer made from a non-metallic material is applied to at least a portion of the interior surface of the body. The non-metallic material is different from the base material.

A method for surface treating a golf club head, includes: (a) forming a depression unit in the golf club head, the depression unit being indented inwardly from an outer surface of the golf club head, the outer surface being divided into a working area and a non-working area, the depression unit being formed in the working area; (b) filling the depression unit with a shielding material and covering the non-working area with a covering material; and (c) sandblasting the golf club head after step (b) and removing subsequently the shielding material from the depression unit and the covering material from the non-working area so as to form the working area into sandblasted and non-sandblasted regions that differ in gloss intensity.

The present invention relates to a method of steel sheet surface treatment, wherein, the method comprises sequentially: a strip surface treatment unit (1) configured with a high pressure spraying device (1-1) or a centrifugal ejecting device (1-2), a strip surface rinsing unit (2), and a strip surface dry unit (3). Either or both of the high pressure spraying devices (1-1) and the centrifugal ejecting devices (1-2) are arranged, and spray onto the strip surfaces with a mixture of solid abrasives and water, i.e., slurry. Additionally, the method of steel sheet surface treatment comprises: a slurry supplying unit (4) and an abrasive recycling unit (5). When the method of the present invention is applied into the strip post processing line, it can control the surface roughness of the steel sheet, while clearing away grease, scales and some contaminations thereon, through impacting the mixture of water and solid particles with a certain ratio onto the surfaces of the strip steel. When the method of the present invention is applied into the finishing processing line, it can control the surface roughness of the steel sheet, while adjusting the mechanical properties of the strip, thereby completely or partially replacing the skin pass process.

According to one embodiment, there is provided a substrate processing apparatus including a processing unit and a manipulator. The processing unit processes a substrate. The manipulator is for maintenance. The manipulator is placed near the processing unit.

The present disclosure is directed to a system and method for in-situ (e.g. on-wing) cleaning of gas turbine engine components. The method includes injecting a dry cleaning medium into the gas turbine engine at one or more locations. The dry cleaning medium includes a plurality of abrasive microparticles. Thus, the method also includes circulating the dry cleaning medium through at least a portion of the gas turbine engine such that the abrasive microparticles abrade a surface of the one or more components so as to clean the surface.

A system is provided for performing a cleaning process of a component of a vehicle. The system includes a first cleaning applicator configured to deliver a cleaning agent to a first surface of the component of the vehicle, a second cleaning applicator configured to deliver the cleaning agent to a second surface of the component of the vehicle, a third cleaning applicator configured to deliver the cleaning agent to a third surface of the component of the vehicle, and a control unit configured to instruct each of the first, second, and third cleaning applicators to project the cleaning agent onto the respective surface of the component for a corresponding predetermined period. The first, second, and third applicators are instructed to project the cleaning agent in a predetermined sequence.

Orthopedic implants produced by additive manufacture, followed by refinement of exterior and interior surfaces trough mechanical erosion, chemical erosion, or a combination of mechanical and chemical erosion. Surface refinement removes debris, and also produces bone-growth enhancing micro-scale and nano-scale structures.
