High intensity shot peening

Claim 2

A high-intensity peening flap construction comprising: an elongate strap of a flexible, resilient, tough, shockabsorbing, tear-resistant material having a high flexural endurance and shape retention, at least one peening particle support base mechanically fastened to said elongate strap adjacent one end thereof, said support base being formed of a metal having the ability to withstand high bending and impact stresses while resisting deformation, and a plurality of refractory hard, impact fracture-resistant peening particles metallurgically joined to an exposed face of said support base.

Claim 3

The peening flap construction of claim 1 wherein two particle support bases are mechanically fastened to said elongate strap adjacent one end thereof, said support bases being equally spaced from said one end of said strap and similarly affixed thereon and said strap being slit perpendicular to said one end between said support bases to permit indepEndent peening action by said peening particles on the respective support bases.

Claim 4

The peening flap construction of claim 1 wherein at least one particle support base is mechanically fastened to said elongate strap adjacent each end thereof.

Claim 5

The peening flap construction of claim 1 wherein said elongate strap is formed of a fiber reinforced polymeric material.

Claim 6

The peening flap construction of claim 1 wherein said peening particles comprise a cemented carbide.

Claim 7

The peening flap construction of claim 1 wherein said particle support base comprises a rivet, the shank thereof extending through an aperture in said elongate strap and being riveted to the strap.

Claim 8

The peening flap construction of claim 6 wherein said particle support base comprises an annealed steel.

Claim 9

The peening flap construction of claim 1 wherein said peening particle support base is fastened to said elongated strap at an acute angle of inclination of the peening face thereof to the length of said strap of from 25* to 80*.

Claim 10

The peening flap construction of claim 8 wherein said acute angle of inclination is from 40* to 70*.

Claim 11

A high-intensity peening flap construction comprising: an elongate strap of a flexible, resilient, tough, shock-absorbing, tear-resistant material having a high flexural endurance and shape retention, at least one peening particle support base mechanically fastened to said elongate strap adjacent one end thereof and at an acute angle of inclination of the peening face of said support base to the length of said strap of from 25* to 80*, said support base being formed of a metal having the ability to withstand high bending and impact stresses while resisting deformation, and a plurality of refractory hard, impact fracture-resistant peening particles metallurgically joined to an exposed face of said support base.

Claim 12

A high-intensity peening flap construction comprising: an elongate strap of a flexible, resilient, tough, shock-absorbing, tear-resistant material having a high flexural endurance and shape retention, at least one peening particle support base mechanically fastened to said elongate strap adjacent one end thereof and at an acute angle of inclination of the peening face of said support base to the length of said strap of from 25* to 80*, said support base being formed of a metal having the ability to withstand high bending and impact stresses while resisting deformation, and a plurality of refractory hard, impact fracture-resistant peening particles metallurgically joined to an exposed face of said support base.

Claim 13

The peening flap construction of claim 10 wherein said acute angle of inclination is from 40* to 70*.

Claim 14

The peening flap construction of claim 10 wherein two particle support bases are mechanically fastened to said elongate strap adjacent one end thereof, said support bases being equally spaced from said one end of said strap and similarly affixed thereon and said strap being slit perpendicular to said one end between said support bases to permit independent peening action by said peening particles on the respective support bases.

Claim 15

The peening flap construction of claim 10 wherein at least one particle support base is mechanically fastened to said elongate strap adjacent each end thereof.

Claim 16

The peening flap construction of claim 10 wherein said elongate strap is formed of a fiber reinforced polymeric material.

Claim 17

The peening flap construction of claim 10 wherein said peening particles comprise a cemented carbide.

Claim 18

The peening flap construction of claim 10 wherein said particle support base comprises a rivet, the shank thereof extending through an aperture in said elongate strap and being riveted to the strap.

Claim 19

The peening flap construction of claim 16 wherein said particle support base comprises an annealed steel.
