TOOLS COATED WITH HTite® ENSURE UNPRECEDENTED OPERATIONAL CONTINUITY DUE TO THEIR EXTRAORDINARY WEAR RESISTANCE.
The areas most subject to wear are coated with alloys with a high chromium carbide and tungsten content.
HT Srl has a wide range of solutions suitable for the coating of wear parts. At the specific request of the customer or according to the application, the following wear-resistant coatings are made :
– HTite ®
– HTite ®SprayCoat
– HTite ®FuseCoat
– HTite ®MigCoat
– HTite ®PTACoat
– HTite ®Braze
– HTite ®Laserclad
It is a technological process that includes both the actual anti-wear alloy and the methodology for its application.
The filler material contains a high percentage of chromium carbides and tungsten carbides.
Deposition of the alloy on the components is carried out at high temperature in a controlled atmosphere, a technique that ensures perfect adhesion of the coating with the base material.
HTite ® anti-wear coating is a top-quality coating with reported material that is in no way polluted or diluted with the base material. It ensures perfect anchorage to the metal of the treated component. It can be applied to complex figures and in positions that are difficult to reach by other coating techniques.
It can have thicknesses ranging from 0.4 to 2.5mm*, greater in the areas of maximum wear and less in the less stressed areas.
With the HTite ®SprayCoat process, powders containing tungsten carbide are used for coating surfaces, blade and knife cutting edges etc.
HT Ltd.’s plants are controlled by Anthropomorphic Robots, which ensure repeatability of processing and high quality of storage.
Subsequent remelting in controlled atmosphere furnaces ensures perfect adhesion of the coating material to the base metal.
All processing steps are carried out in the Coating Department of HT Ltd.
With the HTite ®FuseCoat process, powders containing tungsten carbide are used for coating surfaces, blade and knife cutting edges etc.
HTite ®Fuse plant of HT Ltd. is controlled by Anthropomorphic Robot, which ensures repeatability of processing and high quality of the deposit.
Casting of the alloy takes place during powder deposition in a one-step “hot” process.
HT has robotic welding equipment with controlled axis positioners for surface coating applications with wear-resistant materials and cladding.
Coatings with wear-resistant wire, stellite, stainless steel for small and large series are performed.
HTite ®PTACoat coating is performed on a robotic station to control the welding process in all its stages. The welding process is carried out using a plasma arc that melts the powder onto the surface to be coated. Accurate penetration control allows for high qualities and deposition densities of the materials used.
HT Srl performs coatings using Stellite Powders, Tungsten Carbides, Stainless Steels, Tool Steels and Super Rapids.
With the HTite ®Braze process, alloys with a high tungsten carbide content are deposited in coating thicknesses up to 10 mm. The total absence of dilution in the base metal and perfect adhesion of the braze welding process.
HTite ®Braze is particularly suitable for coating complex figures in small/medium series that do not require surface finishing.
HTite ®HTite ®Laserclad
We have an innovative and powerful laser coating cell. The facility is optimized for high-volume batch processing of components.
The HTite ®Laserclad coating process, ensures high adhesion of the coating to the substrate, with low levels of porosity, minimal deformation due to controlled energy transfer and very high process repeatability.
With this technology, combined with HT engineers’ 30 years of know-how, proprietary powders are applied that optimize component performance while always ensuring competitive pricing.
HT performs heat treatments in-house making use of induction quenching and massive quenching facilities in a controlled atmosphere.
