NO CARB PASTE (ANTICARBURIZING PASTE WATER SOLUBLE) FOR HEAT TREATMENT
[EIRI/EDPR/1439] J.C. 221
INTRODUCTION
Carbon paste (anti-carburizing paste) (water soluble) is a very versatile item meant for application for parts that require no hardness (i.e. to be kept soft) after case hardening. The basic object of the paste alludes to its application for protection of external and internal threads, serratious, blind holes etc.
The specialty of the carbon paste is that it is water soluble and does not chemically invade the steel on which it is applied.
Further, the carbon paste or anti-carburizing paste is steady in its working effect in the furnace at atmospheres of carbon monoxide.
Among other characteristics that the carbon exhibits, a salient one is that it does not absorb moisture from the air during storage.
The formulations of carbon paste comprise carbonates, potassium ferrocyanide, salts of certain organic acids, sodium hydroxide, calcium chloride, rosin soap etc. all-being water soluble chemicals, so water glass (sodium silicate) or glue is used as a binder.
In view of the versatile use of the carbon paste for the end-user industries, the demand of the product is increasing at a rapid pace and it has get very good future prospects.
Decarburization:-
The depth of decarburization is the thickness of the layer in which the carbon content is less than that of the core, i.e. the distance from the surface to a boundary at which the carbon content of the core is reached.
However, to be more precise, from the point of view of functional aspect, the depth of decarburization is the thickness of the layer in which loss of carbon has a significant effect on properties that affect the functioning of the final component.
The limit of this layer can be expressed as a carbon content or a hardness level.
From practical point of view, the depth of decarburization is that it is the thickness of the layer in which the structure differs significantly from that of the core.
Under conditions that cause the oxidation of iron, the oxidation of carbon is also to be expected. Decarburization of a metal is based on the oxidation at the surface of carbon that is dissolved in the metal lattice. It should be noted that, depending on the carbon potential of the surrounding atmosphere, decarburization can take place independently of scaling. However, in heat treatment process iron and carbon usually oxidize simultaneously. During the oxidation of carbon, gaseous products (CO & CO2) develop. In the case of a scale layer, substantial decarburization is possible only when the gaseous products can escape, i.e., when the equilibrium pressures of the carbon oxides are high enough to break the scale layer or when the scale layer is porous.
