Metal Spray coatings engage growth in Agricultural applications. The necessity for cutting/slashing and ploughing means that the components used are subject to very abrasive and corrosive conditions. Metal/thermal spray coatings and hard-facing can provide the solution for wear and corrosion resistance, as well as extended life and increased performance. The necessity for the irrigation of planted crops requires pumps that will withstand the hardness and PH values of the water and fertilizers. Sugar cane crushers and sugar cane cutters also benefit from the Metal Spray process.
The Metal Spray Process Can Apply Ceramics to Pump Seal Areas to Repair and Protect OEM Components Including:
- Knives and blades.
- Threshing components.
- Ground engaging machinery.
Agricultural and Forestry Equipment can be Protected by Metal Spray Coatings Including:
- Barking blades & tools.
- Wear parts for farming tools.
- Feeding screws for fertilizers, and wood bark.
The metal spray and hard-facing processes use various forms of equipment that employ wire, powder and cord to deliver the required solutions.
Each Instance of Abrasion Doesn't Have the Same Solution and Requires a Careful Study of Each Application According to:
- Type and size of the abrasive material.
- Abrasion rate, temperature, impact occurrence.
- Geometry, size and the weld ability of the part.
TufCote® “rope like” hard-facing electrodes to improve abrasion and erosion resistance.
TufCote® is brazed using an oxygen-acetylene torch It can be weld on mild steel, low carbon steel, low alloyed steel, stainless steel, lamellar grey cast iron, spheroid cast iron. It can also be brazed on certain alloys of manganese steel with precautions. TufCote® is weld-able on itself, making local repair or recycling of parts possible.
The powder welding process utilises an oxy-acetylene flame which is ideal for the deposition of smooth, thin, well bonded layers on a wide range of substrates, including cast iron. The hard-facing takes place at lower temperatures, which minimises oxidation and distortion of the work-piece and enables easy surfacing of edges.
