Claims17
A degradable high-strength zinc alloy which includes a) more than 50 wt. % zinc, 1.5-15 wt. % calcium, and three or more of aluminum, copper, magnesium, lead, tin, gallium, lithium, sodium, and strontium, or b) at least 50 wt. % zinc and 2-45 wt. % magnesium and three or more of aluminum, copper, calcium, lead, tin, and gallium;
- said degradable high-strength zinc alloy having a degradation rate of one or more of i) about 10-150 mg/cm2/ hr. in a 3 wt. % KCl fluid at a temperature of 90° C., ii) 0.1-75 mm/day at 50-135° C. in fresh water, iii) 0.1-75 mm/day at 50-135° C. in salt water or iv) 0.01-30 mm/day in a 3 wt. % KCl fluid at a temperature of 90° C.
A degradable high-strength zinc alloy which includes more than 50 wt. % zinc, 1-15 wt. % calcium, 0.1-5 wt. % tin, and two or more of magnesium, aluminum, copper, lead, and gallium;
- said degradable high-strength zinc alloy having a degradation rate of one or more of about a) 0.01-30 mm/day in a 3 wt. % KCl fluid at a temperature of 90° C., b) about 10-150 mg/cm2/hr. in a 3 wt. % KCl fluid at a temperature of 90° C., c) 0.1-75 mm/day at 50-135 ° C. in fresh water, or d) 0.1-75 mm/day at 50-135° C. in salt water.
The degradable high-strength zinc alloy comprising over 50 wt. % zinc, 1-15 wt. % calcium, 0.1-5 wt. % tin, 0.1-5 wt. % gallium, and one or more of magnesium, aluminum, copper, and lead;
- said degradable high-strength zinc alloy having a degradation rate of one or more of about a) 0.01-30 mm/day in a 3 wt. % KCl fluid at a temperature of 90° C., b) about 10-150 mg/cm2/ hr. in a 3 wt. % KCl fluid at a temperature of 90° C., c) 0.1-75 mm/day at 50-135° C. in fresh water, or d) 0.1-75 mm/day at 50-135° C. in salt water.
A degradable tool that is at least partially formed from a degradable high-strength zinc alloy, said degradable high-strength zinc alloy which includes more than 50 wt. % zinc, 1-15 wt. % calcium, 0.1-5 wt. % tin, and two or more of magnesium, aluminum, copper, lead, and gallium;
- said degradable high-strength zinc alloy having a degradation rate of one or more of a) about 10-150 mg/cm2/ hr. in a 3 wt. % KCl fluid at a temperature of 90° C., b) 0.1-75 mm/day at 30-180° C. in fresh water, c) 0.1-75 mm/day at 30-180° C. in salt water, or d) 0.01-30 mm/day in a 3 wt. % KCl fluid at a temperature of 90° C.
