Comparison of brittle materials and plastic materials for mechanical seals:

The brittle material of the high temperature oil pump cartridge metal bellows mechanical seal has a higher anti-adhesion ability than the plastic material. The adhesion failure of plastic materials is often deeper from the surface, and the wear particles formed are larger; while the depth of the adhesion failure of brittle materials is shallow, and the wear materials formed are mostly wear debris. A friction pair composed of materials with large mutual solubility (the same metal or lattice type, lattice spacing, and similar electrochemical properties) is a friction pair composed of two gold or gold and non-metallic materials (graphite, plastic, etc.) Compared with the friction pair composed of metal materials, the adhesion tendency is smaller, so you should pay attention to the negligence when selecting the material pairing.　　408.html,
