SOP - (with Ultrahard Chromium Boride)

SOP - Ultra hard Chromium boride crystals with a hardness second only to diamond, is the ultimate answer to antiwear coating for parts subjected to severe abrasion and particles impact erosion. SOP - Exhibiting a needle like micro-structure provides a hardness of RC 68-72 with a maximum coating thickness of just 1.5 mm only. The unique needle line structure resists penetration by flying particles ensuring highly extended service life of the parts coated with SOP.

SOP has a wide array of applications in continuous process industries such as power, mining, iron ore pelletisation, cement, sugar, paper etc. SOP is being extensively used by Original Equipment Manufacturers (OEMs) of air separators, pneumatic pumps, coal mills, boiler equipment, fans etc., as well.

ID fans, FK pump screws, air separator guide vanes, wear plate liners, coal venturis & pipes, mill discharge valves, coal mill side liners, chutes, scrapers, bamboo chippers , air preheater ducts etc., are only a few of the several applications for this super anti-wear alloy. Wear plates manufactured by using SOP provide buckets of heavy earth moving equipment such as dragline, shovels, wheel loaders etc., freedon from wear.SOP coating can be done by oxy-acetylene as well as carbon arc process.

Remove dust, grease scales etc.. Apply SOP by a brush to a maximum thickness of 1.5 mm. Allow it to dry. Apply a generous carburising flame at a point till the crystals stop glowing. It indicates sweating i.e. bonding of SOP 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 on the surface area and base metal thickness.

On sections exceeding 6mm, carbon arc methods is recommended. Remove dirt, grease, scale etc. and slightly warm the surface. Apply SOP with brush to a maximum thickness of 1.5 mm. Allow it to dry. Use a pointed 6mm/8mm carbofuse (-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. Literature
