Whisker reinforced ceramic inserts

1. The Description of Whisker Reinforced Ceramic Inserts:

   
   

Whisker reinforcement involves strengthening a hard ceramic matrix with strong, stiff, silicon-carbide crystals, commonly called whiskers. When are dispersed into a matrix of fine-grained aluminum oxide, the whiskers add tensile strength and improve the fracture toughness of the ceramic matrix.

Whisker-reinforced ceramics use silicon carbide whiskers (SiCw) to dramatically increase toughness and enable the use of coolant. Whisker-reinforced ceramics are ideal for machining Ni-based alloys(e.g. Inconel), Co-based super alloys (e.g. Stellite) and for roughing hard castings and hardened steel.

2.The Feature and Advantage of Whisker Reinforced Ceramic Inserts:

(1).High hardness (Hv 2,100)

(2).High fracture toughness due to SiC (silicon carbide) whisker reinforced ceramics

(3).Excellent thermal shock resistance, which enables using coolant and interrupted cut machining

(4).Excellent for roughing and semi-finishing operations at 8-10 times faster cutting speeds when compared with carbide grades

(5).Good oxidation resistance due to its alumina substrate

3. The Application of Whisker Reinforced Ceramic Inserts:

(1).Rough and finsh turning HRSA

(2).Milling of HRSA

(3).Turning of hard materials with interruptions

(4). Milling of hard steels (HRC 50-62).
