Cladding of advanced geometries and additive manufacturing

Laser cladding
laser cladding

In Castolin Trio we have two 6kW high density diode lasers from Laserline Inc.

Lasers are supported by 6 axis and 3 axis CNC automatic welding machines, set-up for both powder and hot wire. CAM software packages are available for offline programming of advanced geometries and additive manufacturing of parts.

We have the ability to laser clad large parts up to 15m length, 12m continuous welding. The laser cladding process is supported by the Castolin Eutectic global R&D team with Ph.D. specialists within laser cladding. As manufacturers of powders, Castolin Eutectic can develop customised laser cladding powder/wire solutions tailored to your needs. In our Stavanger workshop, we also own an in-house lab for quality control of powders and new applications.

Tungsten Carbide content up to 60-70% for best wear resistance

Advantages over existing welding technologies
laser cladding
  • Low heat input causing lowest dilution: at 0.5-5% it is considerably lower than PTA and weld overlay.
  • Low distortion: lower heat input means lower distortion of large parts, and less machining time.
  • Faster: up to 7 Kg/Hour deposition rate for Tungsten Carbide containing alloys.
  • High precision, High repeatability; constant and controlled quality.
  • Best wear resistance due to advantages of welding Carbide powder blends with high Carbide content, up to 60-70%.
  • The low dilution and fast cooling rate, gives unique microstructures with exceptional properties.
  • Cladded thicknesses normally in range of 0.3-10mm depending on alloy. Some alloys offer no limitations.

Leader in HVOF coating technologies

HVOF
hvof

Castolin Trio is a leader in HVOF coating technologies, offering both OD and ID HVOF coating. We have two JP-8000 HVOF systems, one cHVOF (ID) and two HVOF cells. One cell benefits from a traverse machine setup for easy handling and set up of parts for coating, the other cell is equipped with a robot for coating complex geometries and inside coating. Our thermal spray coating services are supported by our large capacity of precision grinding and CNC machining. We are also equipped with an in-house lab for quality control of powders and new applications.

Tremendous improvements in component performance 

Advantages and main characteristics
hvof

In contrast to welding, HVOF is a cold process where temperature of parts is kept below 150 °C, hence no thermal impact on the base material. HVOF is ideal for chrome plate replacement.

Typical coatings include high performance materials such as corrosion resistant metals, self-fluxing alloys and carbide blends. The various coatings can offer tremendous improvements in component performance such as wear, heat, oxidisation and corrosion resistance.

HVOF process is supported by the Castolin Eutectic global R&D team with Ph.D. specialists within HVOF. Castolin Eutectic is a manufacturer of powders for HVOF, and thus customized coating solutions can be developed.

HVOF characteristics:

  • Temperature of part kept below 150 °C
  • Adhesion strength ~ 69 Mpa
  • <1% Porosity and low oxide
  • Hardness values of up to 1400 Hv
  • Surface roughness can be achieved down to 0,5 µm.
  • International standards for testing are followed to ensure quality of coating

selective electro

Castolin Trio is a Norwegian representative of the SIFCO selective electroplating process

Selective electroplating
selective electro

Selective brush electroplating is a portable plating method used to improve corrosion, erosion and wear properties, build up worn areas, salvage mismachined parts, as well as repair pitting and damages in base metal.

  • Numerous pure metals and alloys are available using the selective plating process. Most often a combination of Copper build up and Nickel top layer.
  • Copper or silver plating onto premium threaded connections for anti-galling purposes.
  • Accurately controlled deposit thicknesses thus minimizes or eliminates post-machining operations.
  • Can be performed at customer premises.
  • Plated deposits have excellent adhesion.
  • Cold process, typically 15-50 °C.
  • Ideal for small ID repairs
  • Require no or little disassembling of tools
