Eudon Choi, the London fashion week designer, is on coat duty for John Lewis this autumn, creating five different outerwear designs for its Modern Rarity range.
The heavy-duty resin coating is applied on an existing concrete surface, creating a sleek, uniform look.
They hint at the sense of the sometimes dreadful office of President, as when Whitman looked at Lincoln upon attending his second inauguration and saw him "drest all in black, with white kid gloves and a claw-hammer coat, receiving, as in duty bound, shaking hands, looking very disconsolate, and as if he would give anything to be somewhere else".
Built entirely in the USA, it is solid with a heavy duty powder coat.
Results showed a slight increase in tin content and a promising increase in hardness of bronze coating by a decrease in duty cycle at constant average current density.
This coating was produced by changing the duty cycle under ultrasonic agitation during pulse deposition process.
Greater hardness of around 26.5 to 28.0 GPa was achieved for the crystalline over-stoichiometric AlN thin film when the coating was fabricated using a 3.5% duty cycle.
The micro-hardness and corrosion resistance of the coating was enhanced at a low duty cycle and a high frequency (10 Hz in this work), which is related to the increasing amount of SiC particles deposited in the coating.
Those electrons power stop lights, street lamps, billboards–steel items that, before drawing outdoor duty, need to be coated in zinc, or galvanized, to resist corrosion.
When the duty cycle was 45%, the coating thickness reached about 65 μm, where the ratio of outward to inward growth was about 74.67%.
