Text: The Chiefs have won three AFL championships, in 1962, 1966, and 1969 and became the second AFL team (after the New York Jets) to defeat an NFL team in an AFL--NFL World Championship Game, when they defeated the Minnesota Vikings in Super Bowl IV. The team's victory on January 11, 1970, remains the club's last championship game victory and appearance to date, and occurred in the final such competition prior to the leagues' merger coming into full effect.

Text: Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. The term is also used for electrical oxidation of anions on to a solid substrate, as in the formation of silver chloride on silver wire to make silver/silver-chloride electrodes. Electroplating is primarily used to change the surface properties of an object (such as abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
