Nate,
Try the following website: http://www.gesipa.co.uk/ I have had a couple of years experience working with these guys in the Automotive field securing various components, metal and plastic to Aluminium sheet. They also understand the detrimental effects of bimetallic corrosion associated...
Like your self I would never call a split or spring washer a locking device, most of these devices, perhaps with the exception of the Nordlock are really shake proof devices. The only way to add a degree of locking (as no device can be certified 100%) is to either employ a nyloc or allmetal...
What is the required ratio of proof load to tightening torque of a Screw/Bolt, how much of this torque is used to overcome the under head friction and how much is used to put the fastener under tensile load. What is tighteneing to yield?
Try here: http://www.uksteel.org.uk/index.html they produce eiter a book or CD Rom containing the most popular British, European and american steels complete with physical and mechanical property.
Dacromet as described above is an organic coating containing zinc flakes in a paint base, it is applied to the component by either a dip spin process or by spraying, in either case the components will have to be cured at 320 degrees. corrosion resistance via NSS will be in the region of 500...
All the above treatments will give you the same microstructure consisting of mainly martensite and austenite within the case transforming to a mixture of bainite and ferrite towards the core. Spherodising will occurr during annealing from 300 to 600 degrees, but this will be transferred back to...
All of the above are true to some extent. The process that you need to employ for this is a boost and diffuse cycle, wher you would load the surface with a high carbon content atmosphere and then diffuse this in towards the core at a much reduced carbon potential atmosphere. this will control...
