Fracture toughness modification by using a fibre laser surface treatment of a silicon nitride engineering ceramic

Surface treatment of a silicon nitride (Si3N4) engineering ceramic with fibre laser radiation was conducted to identify changes in the fracture toughness as measured by K1c. A Vickers macro-hardness indentation method was adopted to determine the K1c of the Si3N4 before and after fibre laser surface...
