Publish Time: 2019-06-26     Origin: Site

The development of electroless nickel-based alloy technology on non-ferrous substrates in the past decade, especially the electroless nickel treatment technology of light metal aluminum, magnesium, titanium and their alloys, as well as the treatment technology of plastic parts,it is found that pretreatment technology has been developed. It is not only considering the problem of the adhesion between the precision ultrasonic thickness gauge and the substrate, but also considering the instantaneous change of the surface pH of the workpiece when it is immersed in the plating solution, and the influence of different pretreatment methods on the structure of the initial layer of electroless nickel plating and the strip of the treatment liquid. The effect on the performance of the bath. The rational composition of the non-ferrous matrix electroless nickel plating solution was also discussed,it is showing the new development achievements of the technology.


For the measurement of the thickness of the nickel-plated layer on the iron-based and non-ferrous substrates, the general magnetic method and the eddy current method of ultrasonic thickness measurement gauge (non-magnetic method) cannot be measured, and only the Coulomb method (point solution analysis method) can be used to destroy the measurement, and the non-destructive test method is used.


The automatic cladding thickness gauge can be selected from the table to solve the problem you are experiencing. Easy to operate, just rotate the thumb wheel to the end of the scale forward, position the probe on the measuring area, release the self-locking mechanism, and start the automatic measurement and lock, then the coating thickness can be directly displayed on the scale.The correct value, in μm or mm. according to the instructions,they can be used for many years without interruption, for your quality control.The German EPK (Elektrophysik) automatic coating thickness gauge measures the thickness of all non-magnetic coatings on steel (such as paint, powder coating, plastic, rubber, zinc, copper, tin and nickel). Measurements are fast, accurate, and non-destructive. For more than 30 years, the series has become a special instrument for automatically measuring the thickness of the coating. It shows a high level of magnetic coating thickness gauge in terms of process technology and measurement accuracy. Comply with DIN, ISO, BS and ASTM standards.


Fully automated operation of portable ultrasonic thickness measurement has unparalleled features when is used:


1, automatic measurement, no misoperation
2, easy to master with high precision
3, no calibration settings, easy to detect
4, no battery or other power supply
5, automatically display readings
6, with a non-destructive probe, a point of determination
7, metal armor is suitable for outdoor operation
8, anti-mechanical shock, acid and solvent corrosion
The balance device eliminates the influence of the Earth's attractive force and can be measured in any direction and inside the tube.
