Concorde`s final flight :                  

Electroless nickel - density deposited Ni-P-layers in dependence of the phosphorus content  -  DIN 50966, DIN EN ISO 4527

 

     density pure nickel  =  8,9 g/cm3 

 

Measurement of the phosphorus content :

     X-ray, important condition : exact calibration pieces         

     photometric, time-consuming, reasonable, good            

     AAS, Ni-P-layer solving defined amount, quick, good       

     ICP, similar as AAS, quick, very exactly                             

phosphorus content in % density
4 8,5 +/- 0,2
6 8,3 +/- 0,2
8 8,1 +/- 0,2
10 7,9 +/- 0,2
12 7,8 +/- 0,2
