As a materials science expert with a focus on the properties and behaviors of various materials, I can provide an informed answer to your question.
Diamond is the hardest known natural material, ranking a 10 on the Mohs scale of mineral hardness. It is renowned for its exceptional ability to scratch or cut through virtually any other material, including metals and other gemstones. Titanium, while a strong and durable metal, has a Mohs hardness of approximately 6.0, which is significantly lower than that of diamond.
Given the disparity in hardness,
titanium cannot scratch a diamond. In fact, diamonds are often used to cut and shape titanium and other metals in industrial applications due to their superior hardness.
