Anticarb-psl

 (anti-carburising paste for gas carburisation)

Anticarb-psl is specially compounded for selective carburisation of metal surfaces as the paste protects some surface areas which are not to be carburised. Selective carburisation is carried out on surfaces where the wear resistance is necessary on certain areas with high ductility on other areas. It provides a better compromise of a hard abrasive resistant surface associated with highly ductile zone.

Uses :

Anticarb-psl is used for selective carburisation of various metallic parts such as diesel engine components, crane-shafts, gears, bearings, threaded parts, cutting tools, defence components, etc.

Method of application :

Anticarb-psl is a paste which can be applied either by brush, spray or dipping. Water may be used for thinning. Excessive thick coatings should be avoided as it is not only uneconomical but coatings are also prone to cracking. On an average a coating thickness of 0. 5-1 mm is most effective.

Drying :

After application, the parts should be left to dry by suspending in a well ventilated area, preferably in a warm atmosphere. Drying time will vary from 30-60 minutes, and is dependent on the temperature of part and atmosphere.  Drying time will also depend on the thickness of the coating.

Handling :

After the paste is completely dry, the parts should be put in the furnace. Care should be taken at all times to prevent any damage to the coating.

Coating removal :

The best method for removing residual coating after heat treatment is by mechanical action either by wire brushing, sand blasting or manual scraping. Most of the coating however, may get dislodged at the quenching stage itself. High-pressure jetting of a caustic soda solution also facilitates easy removal of the residual coating.

Notes :

1. Always keep the containers tightly closed when not in use.

2. Should the paste get dry in the container, a little water should be added and mixed well.

3. If thinner consistency or coatings are desired then water may be used as a diluent.

4. Cleaning of hands, brushes, etc. Should be done with soap and warm water.
