Agenda

  • To introduce and explain the benefits of the patented technology developed by Pratt & Whitney.
  • To find out interest of the prospects in acquiring the technology on a licensed basis from Pratt & Whitney.

About Dolcera

  • Dolcera is an international services firm specializing in intellectual property and market research services. Our clientele includes several fortune 500 companies and global 100 companies. For more information please visit: www.dolcera.com
  • We at Dolcera are partnering with Pratt & whitney to out-license their green technology to replace Ni-Cd coatings used for finishing purposes.

About Pratt & Whitney

  • Pratt & Whitney is one of the largest aircraft engine manufacturers in the world with a sales revenue of more than $12 Bn and spends more than $250 Mn in research & development.
  • Cutting edge R&D with over a 1000 patents.
  • Has always been at the forefront of technologies for turbine, rocket, reciprocating engines, power systems, etc.

Utility

  • A Tool using this technology has a diamond at a specified precise orientation affixed to the tip of the shank of the machine Enabling markings on various metal surfaces for
  • Identification purposes
  • Surface treatment
  • Surface condition
  • The point of the tool strikes the surface of metal and on impact creates a cold-formed indentation or mark.

  • Stereographic projection triangle for the diamond crystal

Represents a 3D orientation spread out on a 2D plane. Figure depicts the orientation of the diamond tip. It Shows the axis of orientation of the diamond crystal w.r.t three standard orientations of the crystal marked by the 3 vertices.The pole of the crystal should lie within the dotted circle to achieve the super wear resistance orientation

Importance of the orientation

  • Diamond crystals are anisotropic
  • Their mechanical and physical properties vary with their crystallographic orientation
  • The orientation of the crystal governs its strength and wear resistance
  • This particular super wear-resistant orientation has been discovered and patented by Pratt and Whitney.

Limitations of other technologies

  • Carbide and non-oriented diamond indenters have problems such as
  1. Wear and tear of tool head
  2. Replacement costs

Advantages of this tool

  • Economical
  1. Low replacement costs because of increased tool life (up too 100 times that of carbide tools)
  2. Reduced cost per mark
  • Quality
  1. Better reading of 2D markings
  2. Improved marking reliability and quality
  • Physical
  1. Improved wear resistance
  2. Less force required to obtain indention depth

Applications

  • Aero & Industrial Gas Turbines
  • Railway
  • Machineries
  • Weapon markings
  • Punches and Dies
  • Cables and Wires
  • Weapon markings
  • Any metal equipment
