: Dear Sir,

: Could you help us with the following -

: 1)Can babbitt through arc spray process be sprayed to a bond strength of 80.2 N/mm2 ?

: 2) How much would 80.2 N/mm2 be in MPa or psi ?
: 2) According to TAFA Babbit Wire Specifications the coating properties in terms of bond strength will be 2870 psi or 19.8 Mpa, but is 80.2 N/mm2 bond strength achiveable through Arc spray process if so how ?

: 3) If not through arc spray, could you suggest any other process through which the same can be achieved.

: Regards

1) Using conventional process NO, this only provides up to about 30 MPa. Using fluxes and fusing techniques higher values could be possible.

2) 80.2 N/mm2 = 80.2 MPa = 11632 PSI

80 MPa would be about the value you would expect for the tensile strength of these alloys in the cast condition. To get bond strengths anywhere near this, I think you would need to prepare your substrate by tinning and cast or fuse your babbit alloy into place.
