Varying physical properties and chemical composition of active media enable the creation of custom microstructure and performance parameters of surface layers. This is why LINTERPROCESS™ can quickly and inexpensively produce almost any stable and meta-stable surface structure. Particularly effective results were achieved in treatment of Ti alloys by various types of LINTERPROCESS™ technology. When processed with our new LINTERTITANIUM-1™ technology, Ti alloy Ti6Al4V yielded very promising results in creation of diffusion surface layers with distinctive structure and high hardness, wear, fatigue, erosion and heat resistance.

Recently, SANOVA also developed and commercialized new highly effective treatment technology LINTERTITANIUM-1™ specifically for efficient processing of friction-pair components manufactured from Ti and Ti alloys. This technology has been successfully applied and will soon be implemented in mass production in a consumer industry. The following impressive and even unprecedented results were achieved and documented in applications of LINTERTITANIUM-1™:

  • Protective case depth from 5 to 500 microns created in minutes of processing time.
  • Surface hardness from 700 to 2000 Vickers (HV/10) or 60 to 82 HRC.
  • 300% Erosion resistance improvement vs raw untreated Ti.
  • Significantly lower friction coefficient, allowing creation and operation of Ti friction pairs (not yet achievable without LINTERTITANIUM-1™ technology - explained further in this proposal)
  • Strong fatigue performance (10,000,000 operating cycles at 50 ksi load)


LINTERTITANIUM-C1™ Technology

Performance results generated by these new custom technologies were not achievable with the existing processing methods. As a result, SANOVA is currently in negotiations for exclusive licensing agreements for its new LINTERTITANIUM-1™ based technologies with large multinational commercial customers in a number of industries. SANOVA expects strong demand not only for our LINTERTITANIUM™-1 technology, but also for our other LINTERTITANIUM™ treatment technologies such as LINTERTITANIUM-C1™, LINTERTITANIUM-N1™ and LINTERTITANIUM-CN1™ in many areas of component manufacturing.

These new proprietary custom carburizing, nitriding and carbo-nitriding technologies are extremely effective in enhancing surface layer properties.

LINTERTITANIUM-N1™ Technology

Extremely robust carbide, nitride and carbo-nitride thermal protective diffusion layers were created which possessed higher density, hardness and strength. There is a deep secondary transition zone under the carbide and nitride cases, which is saturated with C and N respectively. This zone plays crucial role in supporting the high performance of the protective case and enables fluent transition of surface properties to the metal core. It is important to note, that depth of the protective diffusion surface layers and corresponding chemical composition can be easily varied as needed in SANOVA processing by changing the treatment parameters such as processing temperature and duration of the treatment steps and chemical composition of active medium used in treatment process (C and N potential).
