(R) Plating, Nickel-Thallium-Boron or Nickel-Boron Electroless Deposition
|Publication Date:||1 May 2020|
This specification covers the requirements for an electroless nickel-thallium-boro
This process has been used typically to provide a hard, ductile, wear-resistant surface for operation in service up to 1000 °F (538 °C), to provide uniform build-up on complex shapes, and to enhance solderability of surfaces, but usage is not limited to such applications. This process is not generally recommended for materials subject to over-tempering or high temperature embrittlement when exposed to the post-plating heat treatment of 675 °F (357 °C) for 90 minutes (see 3.3.1 and 220.127.116.11).
The deposits covered by this specification are classified by composition as follows:
Type 1 - Nickel-Thallium-Boro
Type 2 - Nickel-Boron
Unless otherwise specified, Type 1 shall be supplied.
Safety - Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
