False. They are not.
No, articular cartilage does not cover the diaphysis of long bones. Articular cartilage covers the ends of bones where they come into contact with other bones in a joint, providing smooth and low-friction surfaces for movement. The diaphysis of long bones is covered by periosteum, a dense connective tissue that provides support and nourishment to the bone.
Periosteum is a thin connective tissue membrane that covers bones and helps in bone growth, repair, and nutrition.

Articular cartilage or hyaline cartilage.
The largest cartilage in the body is the articular cartilage, which covers the ends of bones where they meet to form joints.

Articular cartilage
Long bone: the ends are called the epiphysis, the shaft is called the diaphysis. There is articular cartilage on either ends. The long bones distally and proximally red marrow. There is yellow marrow in the diaphysis. The yellow marrow is mostly fat. On the surface of the bone is a periosteum which covers the endosteum. The center is called the medullary cavity.
there are 3 types of cartilage. 1Hyaline cartilage: This type of cartilage has very thin fibers having same refractive index as the matrix of the cartilage and thus these fibers are not seen. Hyaline cartilage is the articular cartilage of long bones, sternum, ribs etc. Its color is bluish white and it is flexible. 2Fibrous cartilage: This type of cartilage has numerous white fibers. It is present in the symphysis pubis, and sternoclavicular joint etc. Its color is glistening white and the appearance is opaque. 3Elastic cartilage: This type of cartilage has numerous yellow elastic fibers. It is present in the ear pinna, external auditory meatus, Eustachian tubes, and epiglottis etc. Its color is yellowish and the appearance is opaque.
Cartilage (also known as: articular cartilage)
In adults, the ends of bones are covered by a type of connective tissue called articular cartilage. This cartilage provides a smooth surface that helps with joint movement and cushioning between bones.
