working surfaces on articles working under conditions requiring high resistance to abrasion and cavitation comprises a core of hardenable alloy steel coated with a layer comprising 10-30% marble, 50-80% fluorspar, 2-4% Al powder, 2-8% iron powder, 0.1-6% ferromolybdenum and 0.1-6% Cr are ...
The skin surfaces of boeing and defence aircraft are mainly made of Al alloy material, with Al cladding to avoid electrochemical behaviour. When the aircraft flies continuously, the aeroplanne surface has a greater possibility of affecting erosion as well as wear defect because of high-velocity imp...

the focused electron beam is rastered over each successive layer of powder, which is gravity-fed from powder cassettes and raked into successive layers. This technique allows us to fabricate complex products with freeform shapes and porous structures by controlling the pore size and porosity to mee...
The surfaces of drywall materials defining wall and ceiling surfaces are commonly coated with texture materials. Texture materials are coatings that are deposited in discrete drops that dry to form a bumpy, irregular texture on the destination surface. Texture materials are commonly applied using a ho...
Attempts have been made to use a continuous, autogenous weld inside the tube, without the use of a sleeve, in order to repair damaged tubes. These efforts have failed because the corrosion which led to the damage leaves oxidized surfaces which result in flaws and voids when autogenous welding...

In addition, in the case that the furnace wall surface having a length of one side larger than three times of a diameter of the nozzle is to be spray-coatedly repaired, repairing layer is laminated for every one time of repairing operation for each of divided surfaces having a length of ...
The paste is placed into a tubular shaped mold which is lined with platelet concentrate to coat outer surfaces of the composition. The final dried composition is a cylinder having a diameter of 1.25 cm and a base height of 2.5 cm. Example 3 A bone repairing composition is prepared ...
3, and in general reflector 27 and collector 3 are adapted to illuminate and capture from surfaces occupying space in three dimensions. Some embodiments use a micro-electromechanical (MEMS) scanner reflector to direct the imaging, aiming and therapeutic beams onto the surface. MEMS scanner reflector...
