C-Detect - A Simple Yet Surefire Approach for Analyzing Shim Stocks

摘要

In gaseous carburizing, measurement of the carbon content is an important process. Accurate control of carbon potential and the amount of carbon that is diffused into workpieces are part of that process. It relies on measurements obtained from furnace control instrumentation and carbon analysis to verify the measurement's validity and reliability. Carbon-analysis methods like shim stock essentially verify that readings obtained by the oxygen probe or other control devices are accurate. For proper carburizing treatments, the carbon potential of the furnace atmosphere should be accurately measured and verified. However, a single measurement is not sufficient to get a truly reliable reading. Beyond atmosphere control devices such as probes and analyzers, carbon-analysis methods like shim stock are necessary to validate measurement data. The C-Detect is a new, nondestructive testing tool from Process-Electronic. It quickly and accurately verifies the carbon content of carburizing atmospheres. C-Detect's uniqueness lies in its ability to provide accurate readings regardless of shim handling and its surface condition. Gloves are not mandatory since fingerprints, dust, soot and oxidation will not affect results.
