Coatings and surface treatments for thread forming
Process:
In contrast to tapping, where sections are cut out of the material, thread forming is a non-cutting, pressure forming procedure.
Advantages:
No chip formation
Up to 30% higher surface quality than with thread cutting
Up to 40% higher processing speed than with thread cutting
Threads in through holes and blind holes can be produced with the same tool
Wide range of materials processable
Cutting of thread eliminated
Thread pitch and thread angle errors as with cut threads eliminated
Shaped threads have higher strength owing to non-continuous cut
Requirements: For all shapeable materials with elongation >10 %.
Titanium nitride Titanium carbon nitride
This universal coating is suitable for softer steels TiN Its high level of hardness makes titanium carbon TiCN
and non-ferrous metals. It is only of limited suita- nitride coating very well suited to all steels as well
bility for high-strength steel and stainless steels. as stainless steels, titanium and cast materials
Vickers hardness: 2200–2300 HV above GGG50.
Friction coefficient: 0.5 Vickers hardness: 3000 HV
Temperature resistance: 500–600°C Friction coefficient of steel: 0.2
Colour: Gold Temperature resistance: 400°C
Colour: Blue grey

Titanium aluminium nitride Aluminium chrome nitride
The titanium aluminium nitride coating is suitable TiAlN The aluminium chrome nitride coating achieves AlCrN
for steels and for alloyed heat-treated a very long service life due to its wear resist-
steels, tool steels, high-speed steels, stainless ance, oxidation resistance and high-temperature
steels, titanium, hardened steels and nickel-based hardness. This coating is only suitable for steel
materials. materials in combination with oil as a coolant.
