Surface roughness is a key factor for corrosion resistance in stainless steel, and products must conform to the European standard.
Atomic force microscopy (AFM) is a convenient way to analyse stainless steel surfaces and characterise the surface roughness according to ISO 25178.
In this report, three samples are analysed by using Tosca 400 – the new AFM from Anton Paar.
Radio wave weapon knocks out drone swarms
Probably. A radio-controlled drone cannot be completely shielded to RF, else you´d lose the ability to control it. The fibre optical cable removes...
