← ScienceWhich consequence results when elevated temperature weakens lubrication in ionic pump bearings?
A)Galling accelerates impeller degradation✓
B)Increased magnetic field susceptibility
C)Reduced capacitive reactance occurs
D)Thermal runaway becomes prevalent
💡 Explanation
Higher temperatures lower lubricant viscosity, leading to more friction between bearing surfaces. Thus, adhesive wear, named Galling, becomes dominant because microscopic asperities shear and bond, then tear apart, rather than remaining separated by adequate lubrication.
