Application Procedure

coating can be done by

Oxy-Acetylene as well as Carbon Arc Process.

8/22/2019 Fonpaste_-_1

9/15

Oxy-Acetylene Process: Remove dust, grease scales, etc.

Apply by a brush / spatula to a maximum

thickness of 1.5 mm. Allow it to dry.

Apply a generous carburizing flame at a point till thecrystals stop glowing. It indicates sweating i.e., bonding

of with base metal.

As the bonding proceeds, move the flame along at a rate

sufficient to keep the sweating ahead of the flame. Width of the path depends of the surface area and base

metal thickness.

10/15

Carbon Arc Process:

On sections exceeding 6mm, carbon arc method isrecommended.

Remove dirt, grease, scale, etc., and slightly warm the

surface.

Apply with brush or spatula to a maximum

thickness of 1.5 mm. Allow it to dry. Use a pointed 6mm / 8 mm carbon electrode

(-ve polarity) for fusing.

Provide beads of uniform width with crescent shaped

weaves.

Advance at a rate sufficient to keep surface sweating ahead

of the arc.

Overlap succeeding beads to ensure uniform penetration

Advantages over Competition

Better wear resistance than COMPETITION

since the Chromium Borides are preformed

and we do not add Chromium Carbides to the

paste.

Microstructure - Dentritic & more dense.

Better Fusion Characteristics.
