A solar heat absorber is produced by electrodepositing on a metallic substrate acting as a cathode in a plating bath a black coating including a ternary alloy represented by the formula: Sn-M-Mo where M is Fe, Co or Ni. The electroplating bath contains a stannous salt, a salt of a metal M selected from the group consisting of cobalt, nickel and iron, a molybdate, an alkali metal pyrophosphate, and an amino acid or an ammonium salt of carboxlyic acid or mineral acid. |
