CORROSION PROPERTY OF CAST ALUMINUM IN ENGINE COOLANTS AT HEAT TRANSFER SURFACE
(Two Cells Assembly) |
| |
STANDARDS: ASTM D 4340, JIS K 2234 |
| |
|
| |
A heat flux is established through a cast aluminium alloy typical of that used for engine cylinder heads while exposed to an engine coolant under a pressure of 193 kPa ( 28 psi ). The temperature of the aluminium specimen is maintained at 135°C and the test is continued for 1 week (168 h). The corrosion is estimated on the basis of the weight change of the test specimens. |
