Which outcome is most likely when a hydraulic actuator rod extends rapidly under low load at cold temperatures?

💡 Explanation

When oil viscosity increase at cold temperatures, flow restriction causes pressure drop and the formation of vapor bubbles during rapid actuator extension; immediate collapse of these bubbles creates cavitation on surfaces like control valve poppets. Therefore, cavitation erosion results, rather than simple aeration, stall, or thermal fracture, which have differing causes.
