Ceramic plunger couple are appreciated by engine designer thanks to its high performances such as anticorrosion and wearproof, however which are restricted due to machining difficulty. This article will discuss the feasibility of replacing metal material with silicon nitride ceramics in plunger coupler manufacturing through analysis on change law of stress and displacement of 12150L diesel engine plunger coupler at rated condition, design and develop special clamp for intractable spiral line and oil-out trough, and with satisfactory machining effect.

Sintered Materials

Highly densed silicon nitride ceramics with various α/β phase ratios were produced by pulse electric current sintering process. The β-phase content of Si3N4 in sintered materials varied from 20 to 100 wt% depending on the sintering condition. The microstructure was observed by scanning electron microscopy and investigated by image analysis. Young's modulus, hardness, fracture toughness, and strength were strongly dependent on the α/β phase ratio. The fracture toughness increased from 4.6 MPa m1/2 for 20-wt% b-phase content to 8.2 MPa m1/2 for 95-wt% β-phase content, and the fracture strength showed a maximum value of about 1.6 GPa at 60-to-80-wt% β-phase content.
