[ skleer-uh-skohp, skler- ]

Trademark.

1. a brand name for a sclerometer that determines the hardness of a material by measuring the rebound of a standard ball dropped on the material from a fixed height.

Example Sentences

Page 52 The heat treatment of the finished gears consisted of quenching in oil from a temperature of from 1,420 to 1,440°F. for the No. X-3,340 steel, or from a temperature of from 1,500 to 1,540°F. for No. 6,140 steel, followed by tempering in saltpeter or in an electric furnace at a temperature of from 650 to 700°F. The question has been asked by many engineers, why is the comparatively low scleroscope hardness specified for gears?

From Project Gutenberg

Each finished piston pin, after heat treatment, must show a minimum scleroscope hardness of the case of 70, a scleroscope hardness of the core of from 35 to 55 and a minimum crushing strength when supported as a beam and the load applied at the center of 35,000 lb.

From Project Gutenberg

"Rebounding hardness" is commonly measured by the Shore scleroscope, illustrated in Fig.

From Project Gutenberg

The heat treatment of the finished gears consists of quenching in oil from a temperature of 1,500 to 1,540°F., followed by tempering in oil at a temperature of from 375 to 425°F. Gears so treated will show a Brinell hardness of from 512 to 560, or a scleroscope hardness of from 72 to 80.

From Project Gutenberg

After this quenching, all piston pins are tempered in oil at a temperature of from 375 to 400°F. A 100 per cent inspection for scleroscope hardness of the case and the core was made, and no failures were ever recorded when the above material and heat treatment was used.
