The effect of indium doping on whisker mitigation in tin electroplated on copper has been investigated. Whisker growth studies show that indium addition to Sn effectively mitigates whisker growth. Cross-section images showed predominantly columnar gr

When diethanolamine (DEA) is used as a curative for a DGEBA epoxy, a rapid “adduct-forming” reaction of epoxide with the secondary amine of DEA is followed by a slow “gelation” reaction of epoxide with hydroxyl and with other epoxide. Through

Nickel–phosphorus (Ni–P) coatings with controllable P content and desirable characteristics can be produced by tuning bath chemistry and processing conditions during the electroless process. Although pure medium- and high-P coatings offer a good

Many copper water lines for municipal drinking water in Santa Fe, New Mexico USA, have developed pinhole leaks. The pitting matches the description of Type I pitting of copper, which has historically been attributed to water chemistry and to contamin

Electroless Ni–P coatings offer excellent corrosion and wear resistance and ability to withstand acidic and salt solutions. Medium and high phosphorus Ni–P coatings were produced using plating baths with 10 g/L or 25 g/L of sodium hypophosphite a
