The water heater groundcoat frit was milled in a typical wet mill addition. Firing temperature was 1580 degrees F. Steel surface was a light coil blast. Cobalt and Nickel levels were varied as in the chart below: Subsequent bond ratings were checked, and charted in graph form: 17 Comparison of Cobalt and Nickel in Frit Formulations A smaller amount of Cobalt Oxide was needed to generate the same bond level than a larger amount of Nickel Oxide. About twice as much Nickel Oxide in the frit generated the same bond as Cobalt Oxide.

A water heater (wet spray applied) groundcoat frit, and an electrostatic powder groundcoat frit. The level of cobalt oxide and Nickel oxide was varied in each frit. The bond levels were then compared. The water heater groundcoat frit was milled in a typical wet mill addition. Firing temperature was 1580 degrees F. Steel surface was a light coil blast. Cobalt and Nickel levels were varied as in the chart below: Subsequent bond ratings were checked, and charted in graph form: 17 Comparison of Cobalt and Nickel in Frit Formulations A smaller amount of Cobalt Oxide was needed to generate the same bond level than a larger amount of Nickel Oxide.
