2014-4-10 · Champion Spark Plug Resistor Test . There is no separate resistance check for Champion Aviation spark plugs. The silicon carbide resistor is a high voltage device and cannot be tested with a standard ohm meter. It requires high voltage such as the CT475 cleaner/tester. The CT475 high voltage test does two things.
The results revealed that the silicon carbide ceramic spark plasma sintered at 2 223 K while applying 80 MPa of pressure with a 5-minute soaking time under vacuum has the highest hardness and
