Nitride Bonded Silicon Carbide Providing Enhanced Wear Resistance and Durability

Nitride-bonded silicon carbide boasts excellent oxidation resistance, maintaining strength and bonding ability even at elevated temperatures. Furthermore, this material is extremely tough and resistant to impact damage.

Studies have demonstrated that NB SiC outperforms steel types typically used for soil working parts in light to medium soil conditions; its superior wear resistance surpasses that of boron steel and F-61 padding weld in heavy soil conditions.

Abrasion Resistance

Nitride-bonded silicon carbide stands up well under heavy loads and impacts without incurring damage, and is strong enough to withstand mechanical stress or pressure cracking even at high temperatures.

Studies show that nitride-bonded silicon carbide outshone steel types used for metal-mineral tribology pairs in light soil conditions with loose granules of sand; its wear resistance significantly outshone that of boron steel and F-61 padding weld pads used in medium and heavy soil conditions; its abrasion resistance varied depending on soil grain size distribution; mass wear could be accurately predicted using linear equations.

Cast Refrax NB SiC was designed for industrial environments requiring exceptional durability and longevity, featuring exceptional erosion resistance, thermal shock stability, complex geometric shape maintenance capabilities and minimal downtime due to maintenance downtime. Furthermore, its corrosion-resistance to both acids and alkalis corrosion, and high fracture toughness all temperatures makes Cast Refrax NB SiC ideal for this demanding industry environment.

Corrosion Resistance

Nitride-bonded silicon carbide is an ideal material for use in harsh environments due to its chemical stability, high temperature resistance and good oxidation resistance. Furthermore, it can withstand rapid temperature changes without cracking or fracture, as well as withstanding dynamic loads without fracture or breakage.

Outstanding abrasion resistance can also be found with this material, especially when exposed to light soil containing loose sand particles. In fact, its mass wear resistance surpasses that of XAR 600 steel by up to eight times and even exceeds that of F-61 padding weld layer!

Reaction bonded sialon (RBSC) is produced by reacting a mixture of silicon carbide powder and nitrogen-containing compounds in an electric furnace, yielding dense and mechanically strong composite material with high load-carrying capacity at elevated temperatures. Furthermore, its highly resistant nature to oxidation, acidic environments and alkalis makes it highly suitable as a tribological component in cyclones or dust collection systems.

Thermal Shock Resistance

Nitride-bonded silicon carbide stands up well to extreme temperatures without cracking, making it the ideal material for applications involving high heat such as cyclone linings in coal and mineral processing plants, corrosion-resistant components found in pumps, chemical plants, as well as acids, molten salts and halogens.

NBSIC boasts exceptional load-carrying capacities that far outstrip those of oxide bonded silicon carbide products, and is extremely resistant to impact damage.

Nitride-bonded silicon carbide offers excellent erosion resistance in soil environments. Its wear behavior is determined by soil grain size distribution and typically exhibits linear relationships between friction distance and mass wear, outperforming special steels, padding weld and F-61 wear in light soil conditions while wearing less intensively than these steels in medium to heavy soil conditions.

Nitride-bonded silicon carbide offers excellent corrosion resistance thanks to the formation of protective nitride layers, making it suitable for use in applications such as aluminium smelting and refining plants, glass factories, waste incineration facilities and metallurgical processes.

Mechanical Strength

Nitride-bonded silicon carbide is an ideal choice for demanding environments where resistance to abrasion, corrosion and thermal shock is paramount. Utilizing the Blasch process it can be made into complex geometric shapes for greater efficiency as well as possessing outstanding chemical and refractory properties.

NB SiC boasts excellent abrasion resistance in light soil containing loose grains of sand with significantly lower wear intensity than steels and padding welds used as soil working parts, while offering better resistance to brittle cracking than their steel counterparts.

Tungsten carbide has long been the go-to material for demanding industrial applications, but NB SiC may provide an easier and less costly option. Not only can it form intricate shapes without cracking or breaking, it is an exceptional material for handling nonferrous metals as they melt, resist wear resistance, and protect equipment in harsh environments like chemical production or pipeline system components.
