In recent years, the application of laser plasma spraying technology in the remanufacturing of mechanical parts has attracted extensive attention. Using laser plasma spraying wear-resistant materials to cover the worn surface can not only restore the failed parts, but also improve the service life of materials, which has important application value and good economic benefits.

Next, let's talk about the measuring electrode of the electromagnetic flow sensor
The electrode of the electromagnetic flowmeter is in direct contact with the measured liquid, so it must be corrosion resistant, wear-resistant, leak proof and non magnetic conductive in structure. The three pairs of measuring electrodes are made of 316L, which is suitable for industrial wastewater and weak corrosive acid, alkali and salt solutions, and the price is low. The corrosion resistance of electrode to measuring medium is the first factor to consider when selecting materials. Metal materials other than 316L can be selected, such as molybdenum containing acid resistant steel, Hastelloy B, C, titanium, tantalum, platinum iridium alloys, etc. The grounding electrode is made of the same material as the measuring electrode, which can reliably and stably connect the conductive liquid as the reference point of the differential flow signal with the signal of the converter. It forms similar or approximately equal polarization potential with the liquid, and the instrument can stably output.
