Surface Engineering
Database
This database of Surface
Engineering processes is designed as a reference of all the
available solid engineering data required for making
engineering decisions on the use of hazmat alternatives.
This information is password
protected.
There are a vast number of
coatings and surface treatments available commercially with
more being developed all the time. In general, however,
there is very little performance data available on most of
them. Much of the data that does exist is proprietary,
difficult to access, or has not been taken in a manner
consistent with the requirements of users in the aerospace
and defense industries. Where extensive data exist and are
available, they are provided as downloadable Excel files and
reports. Where data are very limited or unreliable, such
data as is available will be provided, with caveats
included. Information is included on both general surface
treatment processes and materials and on specific commercial
treatments.
This database will grow as we
pull together the available engineering data.
Surface
Engineering Data and Reports:
Most of this data comes from DoD programs and includes
corrosion, wear, fatigue, embrittlement, impact, rig tests
and service evaluations.

Coatings Database
This is a database of basic
engineering properties for a growing list of coatings. This
is the place to go to find information on a specific coating
or trade name. It can be searched by vendor, coating name,
type of coating, application, and any other field in the
database. Data in this database is cross-referenced to the
Surface Engineering Data where it is available. Since there
are many thousands of coatings and surface treatments on the
market, this database will grow to meet user needs. It
currently contains coatings of interest to the aerospace
industry.
