Corrosion properties for selected Sintex alloys after salt spray test. The tests were performed on tensile test rods manufactured at a compaction pressure of 550 MPa and a sintering temperature of 1220 degrees Celcius for the traditional sintered materials and a sintering temperature of 1260 degrees Celcius for the liquid phase sintered materials. (The tests are performed in accordance with the ISO 9227 and ISO 4628-3 standards).
|Definition of corrosion Ri0 – Ri5:||Ri0 – 0% rusted surface area||Ri3 – 1 % rusted surface area|
|Ri1 – 0,05% rusted surface area||Ri4 – 8 % rusted surface area|
|Ri2 – 0,5 % rusted surface area||Ri5 – 40-50% rusted surface area|
*LP = Liquid Phase sintered materials with an optimum additive level.
