In one example, a method for manufacturing an electronic device housing is described. A coating layer may be formed on a surface of a metal substrate. Further, an edge region of the metal substrate may be chamfered by applying water-based anti-corrosion cutting fluid to form an exposed surface portion of the metal substrate. On the exposed surface portion, a transparent protective passivation layer may be formed. Furthermore, a first electrophoretic deposition layer may be formed on the transparent protective passivation layer.

A three-dimensional electrode-ozone oxidation-electrocatalytic membrane coupled wastewater treatment device, including a circulating fluidized bed reactor. The circulating fluidized bed reactor includes a funnel-shaped internal, a truncated cone, a fiber ball filter, a gas-liquid distribution plate, an inner cylinder, an intermediate cylinder and an outer cylinder. The inner cylinder, the intermediate cylinder and the outer cylinder are coaxial.

A method of making a fiber reinforced composite includes: infiltrating a preform having a perimeter with an electrophoretic gel; adding nanoparticles to wells located in the electrophoretic gel outside the preform perimeter; introducing the nanoparticles to the preform using gel electrophoresis; removing the electrophoretic gel to result in a preform having embedded nanoparticles; and infiltrating the preform having embedded nanoparticles with a matrix material or a matrix material precursor.

An electrodeposition coating method includes a degreasing/cleaning step, a chemical conversion step, and an electrodeposition coating layer formation step. The degreasing/cleaning step includes a degreasing step of ultrasonically vibrating a degreasing solution in which a target object is immersed, using an ultrasonic vibrator. The electrodeposition coating layer formation step includes: a first electrodeposition step; a first rinsing step; a rinse water removal/reduction step of removing or reducing rinse water on a rinse water stagnating surface of the target object; a thermal flow step of allowing the first electrodeposition coating film to thermally flow so that the first electrodeposition coating film formed on a portion of the target object near a first counter electrode has a higher electrical resistance than the first electrodeposition coating film formed on a portion of the target object far from the first counter electrode; and a second electrodeposition step.

A vent plug and method are provide for isolating a feature of a part. The vent plug includes a plug receiveable in an opening in the part to form an airtight seal between the plug and the surface of the part. A stem is receiveable in a bore through the plug. The stem includes a cap and a collar. The cap has a sealing surface extending radially from an outer surface of the stem and engageable with a first surface of the plug such that sealing surface overlaps a vent hole extending through the plug. The collar extends radially from the outer surface of the stem and captures the plug between the collar and the cap.
