Wear Resistant Solutions
NAMIC is a wear-resistant solutions provider of advanced materials that successfully increase the service life of components in the environments of abrasion, impact, erosion, corrosion, and heat. Performance alloys and advanced products combined with modern creative techniques are at the core of NAMIC know-how and experience in reducing production downtime, maintenance expenses, and the overall cost of critical replacement parts for the needs of Cement, Mining, Power, Paper, Petrochemical, Chemical, Steel etc.
At NAMIC, when addressing the needs of our customers, we have a wide selection of materials at our disposal. After an in-depth inspection process in which we determine your specific needs, we will be able to provide the most cost-effective and durable material for your situation. Our flexibility in regard to material choice is a major reason to choose us for your next rebuild, as we can respond to any situation without worrying that we have the correct material on hand.
Hardfacings / Overlay:
Hardfacing is the deposition of thick coatings of hard, wear-resistant materials on a worn or new component surface that is subject to wear in service. Generally, Welding processes are generally used to apply the hardfacing layer. Although used primarily to restore worn parts to usable condition, hardfacing is also applied to new components before being placed into service.
In addition to extending the life of new and worn components, hardfacing provides the following benefits:
- Fewer replacement parts needed.
- Operating efficiency is increased by reducing downtime.
- Less expensive base metal can be used.
- Helps reduce overall costs.
Composite Wear Plate:
Composite Wear Plates are designed to deliver a superior performance-to-cost ratio, increasing productivity and extending service life in high wear applications and it has produced using our optimised hardfacing process, Composite WearPlates provide superior hardness, durability and wear resistance, as proven by abrasion and erosion testing compliances. They are bi-metallic plates combining an adaptable steel base with a highly alloyed wear resistant hardface. The low carbon steel base plate allows the product to be welded, bolted or studded to existing structures, while the surface coating provides excellent wear resistance.
Rigorous metallurgical and technical control of all the production steps involved, contribute to the superior quality of WearPlates. High concentrations of Chrome and complex Carbides coupled to an optimised Carbide orientation and unique alloy additions.
Ceramic Coatings:
The ceramic enhanced product range is ideally suited to rebuilding and resurfacing mechanical equipment and components subject to erosion and corrosion in a fluid flow environment. Typical repairs can include pump casings, impellers, heat exchangers, rudders, bow thrusters and valve casings. The products are available in several grades depending on the type of equipment in need of repair and the working environment they operate in.
- Reduction of life cycle cost of key operating equipment.
- Allows engineers to perform preventative maintenance.
- Protection of equipment from erosion, corrosion and chemical attack.
- Reduction in downtime of essential process equipment.
Corrosion Resistant Coatings:
One of the main challenges for metal surfaces is preventing corrosion, Corrosion-resistant coatings can help prevent degradation brought on by oxidation, moisture, exposure to chemicals and more. They provide extra protection to metal parts and function as a barrier to prevent contact between corrosive materials and chemical compounds. Thanks to the versatility in polymer technologies we offer, compatibility and easy formulating, we can provide appropriate solutions with excellent results. Coating that offer protection for metal surfaces with high gloss, high scratch and abrasion resistance, with high flexibility and extremely high chemical resistance. Additionally, we provide direct technical service to even our small-scale clients as we value each equally and understand their pressing needs for the right fit technologies. With first class German products,, we can help formulate coatings that create hard surfaces with resistant film that leaves no cracks and holes, ensuring durable and long-term protection.
Thermal Spray Coatings:
Thermal spraying is preferred for applications requiring minimal thermal distortion of the component and good process control. Typical hardfacing materials deposited by thermal spraying include cermets such as WC-Co and alumina-based ceramics. These coatings are applied to a thickness of about 0.3mm. Spray-fuse coatings, also referred to as self-fluxing overlay coatings, are first applied to the component surface using a flame spraying process. The fused coating wets the substrate surface to produce a coating that is metallurgically bonded to the substrate and is free of porosity. There are various alloy types used with the spray-fuse process, the most important are based on the Ni-Cr-B-Si-C alloy system.
