Magnetostrictive/magnetic material for use in torque sensors
First Claim
1. A kinetically sprayed magnetostrictive/magnetic material, comprising:
- magnetostrictive particles;
magnetic particles with coercivity;
a ductile matrix for bonding the magnetostriction particles and magnetic particles with coercivity together;
wherein an applied magnetic field will align the magnetic particles with coercivity and subsequently the magnetostrictive particles such that the magnetostrictive material will produce a detectable change in the magnetostrictive/magnetic material when placed under an applied stress.

Abstract
A kinetically sprayed magnetostrictive/magnetic material, comprising: magnetostriction particles; magnetic particles with coercivity; a ductile matrix for bonding the magnetostriction particles and magnetic particles with coercivity together; wherein an applied magnetic field will align the magnetic particles with coercivity and subsequently the magnetostriction particles such that the magnetostrictive material will produce a detectable change in the magnetostrictive/magnetic material when placed under an applied stress. A method of forming a composite coating of magnetostrictive/magnetic material on a substrate, comprising: spraying a powder mixture of magnetostriction particles, magnetic particles with coercivity and a ductile matrix in a spray gas stream flowing at supersonic velocity against the substrate to form a composite coating wherein an applied magnetic field will align the magnetic particles with coercivity and subsequently the magnetostriction particles such that the magnetostrictive material will produce a detectable change in the magnetostrictive/magnetic material when placed under an applied stress.
