以下是SSi的陶瓷化处理的特殊保护套管和普通套管在高温和高碳势下的对比情况
Ceragold Probe
Designed for: HIGH temperature and HIGH carbon applications
Driven by concern for the above facts and a desire to improve the Gold Probe performance, SSi has introduced the industry's first "third generation" oxygen probe...CERAGOLD PROBE. We are successfully applying cermet coating techniques to extend probe sheath life and to reduce the catalysis effect with methane that is present with other probe alloy sheaths currently used. This design feature, along with the unique anode contact configuration, is the subject of a recently awarded U.S. patent.
Heat treaters operating equipment at elevated temperatures ( > 1750o ) and carbon potential ( > 1.25% C ) will experience the most significant gain in probe life. The cermet sheath treatment creates a tenacious, un-penetrable layer to protect all exposed surfaces of the probe sheath from the carburizing atmosphere. This reduces the amount of nickel exposed at the surface, reduces soot formation, and virtually eliminates high temperature corrosion (green rot).
CERAGOLD's "on the fly" burn off capability is an additional feature which eliminates nagging probe accuracy and response problems. CERAGOLD is designed with a 1/2" pipe sheath, not 3/4" like other probes. This is intentional because the 1/2" size requires much lower volumes of burn off air to reach the probe electrode tip. This feature greatly contributes to rapid, efficient probe burn off and hence to longer term probe accuracy and process consistency.
