Estimate the maximum expected thermal conductivity for a Cermet that contains 58 vol% titanium carbide (TiC) particles in a cobalt matrix. Assume thermal conductivities of 27 and 69 W/m-K for TiC and Co respectively.

Sagot :

Cricetus

Answer:

The right answer is "36.32 W/mk".

Explanation:

According to the question,

TiC = 76%

or,

      = 0.76

CO = 24%

or,

     = 0.24

Thermal conductivity of TiC,

= 26 W/mk

Thermal conductivity of CO,

= 69 W/mk

On applying the rule, we get

⇒  [tex]"K" \ of \ Cermet=(K)_{TiC} (V_f)_{TiC}+(K)_{CO} (V_m)_{CO}[/tex]

On putting the given values, we get

⇒                            [tex]=(26)(0.76)+(69)(0.24)[/tex]

⇒                            [tex]=19.76+16.56[/tex]

⇒                            [tex]=36.32 \ W/mk[/tex]
