Fig. 15 Example of the use of electroless nickel plating to provide edge retention. The micrograph shows wear damage at the surface of a forged alloy steel Medart roll. Etched with 2% nital. 285× More

Fig. 32 Redesign of castings to provide progressive solidification through the use of tapered walls. (a) Elbow design. (b) Valve fitting design. Source: Ref 31 More

Fig. 10 Marine pile systems provide protection against corrosion and serious physical impact. (a) After surface preparation and application of primer, the petrolatum tape is wrapped around the piling. (b) For mechanical protection, a tough, plastic outer shield is applied over the tape. More

Fig. 5 Dust-collection equipment is commonly used to provide dilution ventilation for dusts generated in field abrasive-blasting containments. Dilution ventilation mixes contaminants with mechanically provided fresh air in the work area to reduce the concentration of airborne contaminants. More

Fig. 8 Baked coatings on standing seam roofs provide long-term color and gloss retention. More

Fig. 15 Flap hinge forged in dies designed to provide uniform flash around the forging and to shift flash impression from upper to lower die. Dimensions given in inches More

Fig. 15 Forging positions for a sway brace fitting that provide for (a) a straight parting line or (b) a broken parting line. Dimensions given in inches More

Fig. 16 Flute geometry of drills modified to provide chip-breaking action through the addition of a rib (a), a radius (b), or a notch (c) to the drill flute More

Fig. 10 Various sealing methods that have been used around the sheet to provide a pressure seal suitable for containing the gas pressure during forming. Sections (a) and (b) use seal beads machined into the tooling, and (c) shows the use of a superplastic frame used as a soft gasket. More

Fig. 15 Casting in which six cored holes were added to provide core support needed to prevent core distortion when molten metal filled the cavity. Dimensions given in inches More

Fig. 15 Use of an adjustable bipod foot assembly to provide three-point contact, ensuring perpendicularity of stud to workpiece More

Fig. 21 A hub casting with a pad to provide a feeding channel from the riser. (a) Top view. (b) Side view More

Fig. 3 Induction coil with an offset used to provide heating uniformity More

Fig. 7 Schematic showing selected methods used to provide a plasma near the substrate. (a) Hot cathode configuration. (b) Magnetically confined plasma configuration. (c) Unbalanced magnetron configuration More

Fig. 5 Some of the lower-priced grades of steel that can provide suitable mechanical properties can be determined from these curves. Selections from this chart will be on the safe side because mild quenching was used in its preparation. WQ, water quench. Source: Ref 2 More

Fig. 26 In induction hardening, a design may have to provide a nonuniform section to even out the heating rate, as illustrated in this large, coarse pitch sprocket. More

Fig. 14 Apparatus used to provide consistent alumina suspension concentrations and flow rate to the platen surface. Also shown is a pint bottle containing the same alumina suspension for hand polishing composite samples. More
