The areas most subject to wear are coated with alloys with high chromium carbide and tungsten content.
The areas most subject to wear are coated with alloys with high chromium carbide and tungsten content.
HT Srl has a wide range of solutions suitable for the coating of parts subject to wear. On specific request of the customer or according to the application we realize the following anti-wear coatings:
– 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 and tungsten carbides.
The 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.
The HTite ® anti-wear coating is a coating of the highest quality with reported material that is not in any way polluted or diluted with the base material. It ensures a 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 variable thicknesses from 0.4 to 2.5mm*, greater in the areas of maximum wear and less in the less stressed areas.
The HTite ®SprayCoat process uses powders containing tungsten carbide to coat surfaces such as the cutting edges of blades and knives, etc.
HT srl plants are controlled by anthropomorphic robots, which guarantee repeatability of processing and high quality of the deposit.
Subsequent remelting in controlled atmosphere furnaces ensures perfect adhesion of the coating material to the base metal.
All processing phases are carried out in the Coating Department of HT Srl.
With the HTite ®FuseCoat process, powders containing tungsten carbide are used for the coating of surfaces, cutting edges of blades and knives etc..
The HTite ®Fuse plant of HT srl is controlled by an anthropomorphic robot, which guarantees repeatability of the processing and high quality of the deposit.
Casting of the alloy occurs 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.
We perform coatings with wear-resistant wire, stellite, stainless steel for small and large series.
The HTite®PTACoat coating is carried out on a robotic station for the control of the welding process in all its phases. The welding process is carried out by means of a plasma arc which melts the powder on the surface to be coated. The accurate control of the penetration allows to obtain high quality and density of deposition of the materials used.
HT Srl performs coatings using Stellite powders, Tungsten Carbides, Stainless steels, Tool steels and super fast.
With the HTite ®Braze process, alloys with a high tungsten carbide content are deposited in coating thicknesses of up to 10 mm. The total absence of dilution in the base metal and the perfect adhesion of the brazing process.
HTite ®Braze is particularly suitable for coating small.medium runs of complex shapes that do not require surface finishes.
We have an innovative and powerful laser coating cell. The system is optimised for processing large runs of components.
The HTite® Laserclad coating process ensures high adhesion of the coating to the substrate, with low porosity levels, minimal deformation due to controlled energy transfer and very high process repeatability.
With this technology, combined with HT's thirty years of expertise, proprietary powders are applied to optimize component performance while always ensuring a competitive price.
HT performs heat treatments in-house using induction quenching and mass quenching systems in a controlled atmosphere.
