IVD of Aluminum

DEPOT MAINTENANCE PROJECT as of 940923

Type: E/T
Accession Number: 11800
Code: Active

Narrative:
The IVD aluminum process is an alternative for replacing cadmium and nickel-cadmium electroplating on 80% of parts cadmium plated at McClellan AFB. This technology offers decreased environmental contamination, improved plating performance over cadmium based systems.

Funding: $660K
Application/Source: Electroplating
Pollutant Category: Heavy Metals, Cyanides, Acids

Comments: Three tests are required IAW MIL-C-83488; (1) thickness test; (2) adhesion test, and (3) salt spray test. The following parts have been ivadized: F-15 ribs, F-111 horizontal stabilizer intercostals and outboard bearing housing, "L" cylinder, B-52 piston. Thickness and adhesion tests performed with desired results on the following parts: F-15 ribs, F-111 horizontal stabilizer intercostals and outboard bearing housing, "L" cylinder and B-52 pistons. Still undergoing salt spray test for the above parts. Salt spray testing passed on corrosion panel for calibrating chamber. (No production part in relation to corrosion panel.

Plating - IVD

DEPOT MAINTENANCE PROJECT as of 940923

Type: E/T
Accession Number: 37927
Code: Cancelled

Narrative:
Ion Vapor Deposition is a process by which aluminum is vaporized and adheres to parts. The process requires strict controls, a vacuum, proper air conditioning, dehumidifying, and avoidance of contaminates.

Funding: $900K, (FY91)
Application/Source: Substitution for cadmium plating
Pollutant Category: Heavy metals
Governing Regs/Laws: CWA, RCRA

IVD

DEPOT MAINTENANCE PROJCET as of 940923

Type: E
Accession Number: 8973
Code: Completed

Narrative:
Cadmium is the major contaminant and in some cases the only reason for a waste being classified as a hazardous waste. Reduction in the amount of cadmium being used will help minimize HW. Unit installed for IVD of aluminum vice use of cadmium coatings where possible.

Funding: $350,000
Application/Source: All Wastes Contaminated with Cadmium
Pollutant Category: Solid Waste
Governing Regs/Laws: RCRA

Status:

Initial Submission Date: 1987-07-01
Update Submission Date: 1994-04-29

DEPOT MAINTENANCE PROJECT as of 940923

Type: E
Accession Number: 8989
Code: Completed

Narrative:
This project will replace nickel-cadmium (Ni-Cd) plating with a nontoxic substitute, IVD of aluminum. Alternatives considered/reasons deleted : Continued use of nickel cadmium plating/continued worker exposed to toxic substances, high disposal costs, failure to reduce waste generation. Benefits: Elimination of the following waste streams associated with Ni-Cd plating: plating solutions, contaminated rinsewaters, blast waste. Less worker exposure to hazardous substances. Compliance with the federal requirement for implementation of a waste minimization program. Impact if not provided: Failure to achieve waste minimization goal.

Funding: Cost: $337,000; Anticipated Fund Source:
Pollutant Category: Electroplating Solutions and Rinsewaters, Blast Media

Lessons Learned: Threaded components for Kelly's workload are not being processed through the IVD process as yet because torque tension values need to be determined for the aluminum coatings applied. Warner-Robbins is processing their threaded components and using a lubricant upon installation to compensate for differences in torque tension values. Have experienced a series of equipment problems resulting in increasing amounts of downtime.


DEPOT MAINTENANCE PROJECT as of 940923

Type: E
Accession Number: 8994
Code: Completed

Narrative:
The ION Vapor Deposition system will replace cadmium electroplating with IVD of aluminum. Alternatives considered/reasons deleted: Continue to cadmium plate - this has the continuing disadvantage of cadmium waste generation, potential for worker exposure to toxic material and difficulties treating cadmium at the IWTP. Benefits: Superior corrosion protection. Will reduce the generation of cadmium contaminated waste from the plating and blasting processes minimizing waste treatment and disposal cost and potential worker exposure. Impact if not provided: F-15 workloads will continue to be contracted out. Toxic cadmium waste (rinsewater and blast media) will continue to be generated unabated.
