Cross cut test fails, conical bend test fails, free drop test fails. Strangely whilst looking for a pot I discovered that some cheap Chinese pots are 316. Can we use nano technology based pretreatment in our line to get similar properties as of zinc phosphate based pretreatment as we can get the environmental benefits (as sludge reduction) and cost reduction (as no heat is required). Zinc phosphate cement is used for cementation of inlays, crowns, bridges, and orthodontic appliances and occasionally as a temporary restoration. 1. Q.

Dissolve zinc in acid.Take 6,5 parts of this solution and mix it with 316L stainless steel is the ideal way to go if you can afford it. As intended very little of it if any at all dissolved. I then added 90 grams of NaNO3 (22.5g/L) and ran another test specimen at 90 °CC. When solution cooled I had a mixture of white and black precipitates at the bottom. Q. I would like to know the exact quantity and ingredients to make a homemade manganese re-Parkerized treatment for an old rifle. Cleaning is paramount prior to coating and it can have a significant effect on the growth rate of the phosphate coating, its thickness, and the crystal size. A. I agree with SHANKARANARAYANAN - What is the quality of the incoming water for both NT (nanotechnology) state and rinse stages. Do you have a formula for Manganese Phosphate solution ? Nickel Acetate One doesn't have to use pyrex containers for parkerizing. Although there are variations, it typically consists of the following steps: clean, rinse, activating rinse, zinc phosphate, rinse, and seal. I usually let the part remain in the solution for a total of 20 minutes (less MAY work, but I was told 20 minutes so that's what I used and it worked marvelously). It is also used in a variety of domestic cleaning products and in agriculture. Bring the solution to an extremely slooowwww rolling boil . - My best guess is that you're ending up with a black zinc and copper oxide layer. The parts should be totally immersed in the solution, being careful that anywhere the wire touches the part won't show on the finished part (usually easy to do -- like in the firing pin hole of a bolt). I am trying to do manganese phosphating home-brew coating. To minimize search efforts and to offer multiple viewpoints, we combined previously separate threads onto this page. - Have you costed in the essential effluent treatment facility. Isn't manganese phosphate insoluble in water ? We've corrected your typo about the magnetic characteristics of stainless steel grades. You can usually get this stuff from a machine shop or from Q. A. 2. Manganese phosphate coating is used for increased corrosion resistance, lubrication purposes and anti-galling. Mix to dissolve. } Ed. Sorry, and good luck. A 5X solution must be diluted 5 times to make a normal dilution, while a 10X solution must be diluted 10 times. Use slightly less than one gallon and it won't boil over when you add the items, slowly, to the roiling solution. "Phosphating & Metal Pretreatment" Apart from the parameters such as temperature and time of coating what else can affect the thickness of coating. immersion(30-180 minutes).Dry without rinsing, then oil, wax or lacquer . Once you have bead blasted the part, you should handle the part with gloves (never greasy hands) and store them wrapped in clean paper towels awaiting the Parker Bath. For sealing the two ends...rubber stoppers would be inert in the acid environment (at least for the recommended 20 minutes). "background": "#fff", This is done by dipping a strip of iron-test paper in the phosphate solution. This is a learning project for me. Best Regards. How much water to one jigger of acid? Thanks, Antonio. Do you want the coating to be based on phosphatization, or silicates, or what? Added 6g of iron in the form of 0000 steel wool.
