TiN COATED AND HARD CHROME THREAD GAUGES

Titanium Nitride is a ceramic coating
which is applied by pvd (Physical Vapour Deposition) to a high speed steel substrate. The coating is very hard (2300 HV 0.05), abrasion resistant and corrosion resistant, and is applied at a temperature of 500°C to the substrate.
Coating thickness is typically 2 to 5 microns.
The TiN coating is a ceramic, so when it is in direct contact with a ferrous component, there is no galling. Thus, wear life of the coated gauge is significantly higher... between 5 and 7 times the life of a conventional gauge, depending on application.
These high-performance, high-specification gauges are available from stock for standard sizes and on short lead times for make-to-order.

TiN Coated Screw Ring Gauges
TiN Screw Rings are supplied to order and have similar benefits to screw plugs. Consult the company for further details.
HARD CHROME SCREW PLUGS
AND SCREW RINGS
These are made-to-order and provide a hard, wear-resistant coating to the gauge. Plating is typically 6 microns on diameter and gauge life is extended by a factor of 2 or 3, compared with a conventional gauge, Double-ended plug gauges are usually supplied as a TiN coated go and conventional tool steel no go.
